i tried execute script in webdriver following latest versions of eclipse, selenium server , firefox, firefox gets executed , script not execute further: eclipse luna service release 2 (4.4.2) selenium jar selenium-server-standalone-2.45.0 firefox 36.0.4 , firefox 38 beta version however, when used firefox 32.0, scripts runs completely. what technical reason behind non-compatibility of latest firefox version latest eclipse , selenium jar? please see here in changelog. seems mozilla has rewritten of there apis not available selenium relied on this. changelog v2.45.0 important changes in release: native events in firefox relied on api mozilla no longer provides. such, fall synthesized events on recent firefox versions. i have been looking latest firefox version supported. other people have found same problem , rolling using v35.0.1 see here

i developed android app used application.registeractivitylifecyclecallbacks ( http://developer.android.com/reference/android/app/application.html ) know when each activity started , stopped , record analytics purposes. developing ios version , cannot find equivalent method monitor uiviewcontrollers or uiview displayed app. anybody has idea ? beginner on ios may not taking right approach, feel free suggest other ideas. edit after first answer felt should more precise. developing sdk other developers include in apps want impact of sdk on code small possible. i first thought doing baseactivity / baseuiviewcontroller developers have extend in activity / uiviewcontroller felt heavy , since both language don't allow multiple inheritance impact code. why registeractivitylifecyclecallbacks method great in android because have give me application or activity object. is there solution ios or have create basecontroller ? thank in advance. i've not run specifi

after doing research on android patterns kept finding different answers. people start talking design pattern, architectural or architectural presentation patterns. i'm reaching conclusion architectural presentation pattern mvc architectural pattern while mvp & mvvm design pattern on same rank design pattern observer. correct? design pattern general reusable solution commonly occurring problem within given context. reside in domain of modules , interconnections. connected code. on other hand architectural patterns similar software design patterns have broader scope . describing overall pattern followed entire system. for me mvc, mvp , mvvm architectural patterns other architectural patterns may hear off (the list not exhaustive) : event driven architecture cqrs rest microservices soa pipe & filter architecture you can find examples on wiki : http://en.wikipedia.org/wiki/list_of_software_architecture_styles_and_patterns

this continuation of previous thread because none of answers there produced intended result. getting super wierd behavior using regexes match dates. want match following dates: [month-day] such as: "[01-23]" // january 23rd valid date "[02-31]" // february 31st invalid date "[02-16]" // valid "[ 6-03]" // invalid format here regex: regex = /\[^[0-1][1-9]\-[0-3][0-9]\]/ i tried put both single \ , double \ infront of brackets nothing seems working matching these dates. ideas? thanks! the problem regex placement of start-of-line anchor ^ after initial square bracket. cannot happen, regex never matches anything. move anchor beginning of expression fix problem: regex = /^\[[0-1][1-9]\-[0-3][0-9]\]/

i have issue symfony 2.6 form collections. removing elements collection works, when @ least 1 present. if last element removed dom (leaving collection container empty), no elements removed collection after handling request. example: i have form collection "children" , 2 children, "a" , "b". remove child "b" dom, save, removechild called, child removed. remove child "a", save, nothing happens - after refreshing form child still present. when dumping main entity after form has handled request, child present in it's collection well. did have similar problem , found solution? you can 2 methods : as in symfony doc : form collection doc or doctrine annotation : doctrine orphanremoval doc but don't forget cascade={"remove"} annotation

i newbie on pam , nss please gentle. i have following scenario: i have access ldap database have no control on administration (so please not proper fix fix database, know not happen). however, in database users registred , authenticate against not have maintian own user database. the main problem there no uid or gid information in database , ldap admins refuse add information. my idea: configure pam can authenticate against ldap. if user sucessfully authenticates, pam (via pam-script?) creates local user (in /etc/passwd) local unique uid. local user later used nss find uid , guid. what have done far , question: i can authenticate against ldap , have idea on how create user @ login failing make nss use "local users" getting uid , gid. how can split login use ldap authentication , uses local files finding uid , guid, shell etc ?

javascript has arrays use numeric indexes ["john", "bob", "joe"] , objects can used associative arrays or "maps" allow string keys object values {"john" : 28, "bob": 34, "joe" : 4} . in php easy both a) sort values (while maintaining key) , b) test existence of value in associative array. $array = ["john" => 28, "bob" => 34, "joe" => 4]; asort($array); // ["joe" => 4, "john" => 28, "bob" => 34]; if(isset($array["will"])) { } how acheive functionality in javascript? this common need things weighted lists or sorted sets need keep single copy of value in data structure (like tag name) , keep weighted value. this best i've come far: function getsortedkeys(obj) { var keys = object.keys(obj); keys = keys.sort(function(a,b){return obj[a]-obj[b]}); var map = {}; (var = keys.length - 1; >= 0; i-

i have old script contains variant of sort +0 -1 , man sort in system not mention existence of these options. from another question , led the wikipedia page sort , says: in old versions of sort, +1 option made program sort using second column of data ( +2 third, etc.). deprecated, , instead -k option can used same thing. but not mention negative argument such -1 supposed do. note that, in "modern" sort (gnu coreutils 8.21), sort +0 -1 works, while of following fail: sort +0 +1 , sort -0 -1 , , sort -0 +1 . i can add pairs of numbers (e.g. sort +0 -1 +2 , sort +0 -1 +2 -3 ), short test case cannot precisely infer meaning. edit : completeness, nowadays invalid command such sort +0 +1 equivalent sort -k1 -k2 . as per gnu info page on sort : on older systems, ‘sort’ supports obsolete origin-zero syntax ‘+pos1 [-pos2]’ specifying sort keys. obsolete sequence ‘sort +a.x -b.y’ equivalent ‘sort -k a+1.x+1,b’ if y ‘0’ or absent, otherw

i have calendarpicker eventfilter. in eventfilter want displayedcalendar calendarpicker.getdisplayedcalendar(), wrong date. last date before calendarpicker update displayedcalendar. it seems eventfilter executed before standard events of calendarpicker. and cannot use eventhandler because event consumed calendarpicker. for example: - see march 2015 in calendarpicker. - change month april 2015 - in calendarpiker.addeventfilter() calendarpicker.getdisplayedcalendar() "2015-03-01" - calendarpicker shows april 2015 how can execute standard events before eventfilter? here code: calendarpicker.addeventfilter(mouseevent.mouse_clicked, new eventhandler<mouseevent>() { @override public void handle(mouseevent event) { if (event.getbutton().equals(mousebutton.primary)) { calendar cal = calendarpicker.getcalendar(); if (cal != null) { selecteddate = cal.gettime(); log.debug(string.format("(selecteddate): %s" , selecteddate));

in implementation of jira, have custom field called developer gets populated automatically (username) whenever move jira open fixed state. want similar fixed reopen transition. is, whenever tester changes status reopen, should go developer or project lead (in case field isnt populated custom field can overridden). i tried implement post function, there isn't way can use or criteria. or there way? you can post function on transition using script runner plugin if self-hosted jira instance allow great flexibility in logic fill target field in.

i using rad grid display information grid checkboxes mark items , using raddropdownlist can pick action , press button it. 1 of items send email emails of checked rows. in button click call enumerate checked rows grid , put emails in string buffer , add script execute email on postback bring email. clientscript.registerstartupscript(this.gettype(), "mailto", "<script type = 'text/javascript'>parent.location='mailto:" + emailtobuffer.tostring() + "'</script>") ; this results in line <script type = 'text/javascript'>parent.location='mailto:dana@here.com; '</script> put in front of telerik rad javascript code in html. somehow innocent little line of javascript causes master checkbox on radgrid header line , raddropdownlist stop functioning completely. dropdown list not drop. value parent.location no else in view source html except inserted email line. i cannot figur

i'm building app touch screens , has on screen keyboard them use. works wonders desktop computers, not mobile devices have built in keyboards. i have been looking around see if there way detect if on desktop or mobile, have seen has been deprecated. there way so? can enable library if on desktop computer. you can accomplish doing: if(/android|webos|iphone|ipad|ipod|blackberry|iemobile|opera mini/i.test(navigator.useragent)){ //your code mobile devices } here fiddle: http://jsfiddle.net/mnbw23gg/

i have uisplitviewcontroller uitabbarcontroller master. uitabbarcontroller contains 1 uinavigationcontroller uitableviewcontroller root (it main menu of app). after tapping on cell in main menu , in uisplitviewcontroller 's detail part uitableviewcontroller should presented (let's call detail view ). in landscape mode works ok. but in portrait, whet tap on cell in main menu , detail view presented modally, , not pushed, supposed to. also, when rotating landscape portrait, main menu presented instead of detail view , , after click on main menu 's position show detail view , presented modally no possibility rotate or go back. removing uitabbarcontroller , setting uinavigationcontroller uisplitviewcontroller 's master works want (in landscape mode have menu | detail views side side , in portrait mode controllers behave on regular uinavigationcontroller ). uitabbarcontroller gone. what i've tried: every possible segue type - none of them

my grails application using shared legacy database. there no foreign key constraints explicitly defined in table schema. there are, logical foreign key relationships present in many of tables. not allowed change db schema (as shared db, take permission dba... ...). is there way define hasmany, manytomany , other gorm constraints without changing existing database schema? you can have hasmany , belongsto without foreign keys. cascade delete , other things work, wont fk violations errors if code thing violates fk.

i'm trying use splinter library in python. when use from splinter import browser in code gives me: file "d:\users\user\desktop\splinter.py", line 1, in importerror: cannot import name browser i trying run file desktop. why looking on desktop splinter.py? there no splinter.py on desktop. fixed: there file named 'splinter.pyc' on desktop before file named correctly. deleting fixed problem.

i have binary bitmap 10bits. every bit represents 10%. there simple math function sum of percent bitmap? sample 0000000000 = 0% 0000000001 = 10% 1000000000 = 10% 0000100000 = 10% 1000000001 = 20% 0000000011 = 20% 0000110000 = 20% 0010000010 = 20% 1010000010 = 30% be aware example of how bits activated. number have int such 0,1 1023. you don't have use loop. don't have math. this: var number = 1000100010; alert(number.tostring().split("1").length - 1); //a little more deep: var number2 = 1100100000; alert((number2.tostring().split("1").length - 1) * 10 + "%");

i'm developing android chat application using quickblox.. app : user logs in , chooses user chat with.. (not in roster).. managed users using following code : retrieveallusersfrompage(1); private void retrieveallusersfrompage(int page){ qbpagedrequestbuilder pagedrequestbuilder = new qbpagedrequestbuilder(); pagedrequestbuilder.setpage(page); pagedrequestbuilder.setperpage(100); qbusers.getusers(pagedrequestbuilder, this); } int usernumber = 1; @override public void onsuccess(arraylist<qbuser> users, bundle params) { for(qbuser user : users){ this.users.add(user); usernumber ++; } int currentpage = params.getint(consts.curr_page); int totalentries = params.getint(consts.total_entries); if(usernumber < totalentries){ retrieveallusersfrompage(currentpage+1); } } but wanna filter them add available(online) users.. can't find way that.. idea ? with no roster can use next trick user.las

on windows, compiled using mcc matlab script takes struct parameter , writes output file. when try call on windows' cmd using func.exe "struct('field','data')" or func.exe struct('field','data') i get attempt reference field of non-structure array. error in func (line 3) matlab:nonstrucreference passing struct uncompiled script through matlab works, e.g. matlab /nosplash /nodesktop /r "func(struct('field','data')),exit" assuming still wish pass struct , not distinct arguments (so can specify optional arguments run), there workaround? (google didn’t help!) thanks! with info daniel , navan, workaround implemented (given argument called args) is if (ischar(args)); evalc(sprintf('args=%s;',args)); end which works both in compiled executable , calling directly within matlab. assumes user has done sanity checking.

i have string formatted follows permanent way: { first nested string; { second nested string; } } nesting may arbitrary depth. each sub-element formatted closing brace, adding 2 spaces previous level of nesting , closing brace. want receive regular expression allows obtain nested data. example, above example result should be: first nested string; { second nested string; } i wrote following code allows parse strings in 1 line, symbol '.' character except newline. regex regex("\\s*\\{\\s*(.*?)\\s*\\}\\s*"); string testinput = "{\n" " first nested string;\n" " {\n" " second nested string;\n" " }\n" "}\n"; smatch match; if (regex_search(testinput, match, regex)) { auto result = match[1].str(); } what regular expression make can receive nested data? in advance. the regex implementation c++ standard library not support recursion, needed match nested structures. like

i trying create named set return sum of selected members measure. when deploy getting error function expects tuple set expression argument. string or numeric expression used. please review code , suggest solution. have dimension named uline , named set should sum selected 4 members of dimension measure sum({[uline].[cu - (46)], [uline].[fru - (45)], [uline].[gl - (38)], [uline].[pu - (44)]},[measures].currentmember) better use aggregate rather sum if wish available measure. also no need include measures hierarchy inside function. so try simpler this: aggregate( { [uline].[cu - (46)], [uline].[fru - (45)], [uline].[gl - (38)], [uline].[pu - (44)] } ) please note though new member in existing hierarchy, this: with member [uline].[aggset] aggregate( { [uline].[cu - (46)], [uline].[fru - (45)], [uline].[gl - (38)], [uline].[pu - (44)] } ) select [measures].[somemeasur
