i have code in scala when define a value, call methods in object setstr , useful , amazing. when define aclass final, compiler throws exception illegal inheritance final class. in cases should use final classes , type of method calling after class initiation useful me, , question how solve problem test("test function call") { val a: aclass = new aclass { setstr("pooya") func1(this) } } class aclass { // when declare class final, compiler raise error private var str:string="" def setstr(str:string)={ this.str=str } def amethod() = print(str) } def func1(a: aclass) { a.amethod() } when new aclass { ... } creating anonymous class extends class. when class final cannot extended. one way want that: val a: aclass = new aclass import a._ setstr("pooya") func1(this) following @vladimir's suggestion, cleaner way: val a: aclass = { val = new aclass import a._ sets

when login username , password bcrypt checks no problem, fine. but when go through process of recovering password , try login new password bcrypt never returns true. the code have follows: before_save :encrypt_password before_update :encrypt_password def authenticate player = player.find_by(mail: self.mail) unless player.nil? current_password = bcrypt::password.new(player.password) if current_password == self.password player else nil end end end private def encrypt_password unless self.password.nil? self.password = bcrypt::password.create(self.password) end i'm using rails 4 you don't need before_update callback. when creating new record (user in case), before_save triggered. right behavior. but when updating record, both before_update , before_save triggered, means password column encrypted twice. that's why unexpected behavior. check this page more information callbacks. what's more, think it&#

i learned close html tags img , meta etc. this: <img src="..." /> <meta charset="..." /> <hr /> <br /> <input type="..." /> but i've seen numerous sites don't put /> @ end. put > @ end. results in: <img src="..."> <meta charset="..."> <hr> <br> <input type="..."> but me doesn't seem right... how can browser know if tag still needs closed somewhere when that? that's how learned years ago. but twitter bootstrap closing input tags without /> @ end. is valid html? , preferred way of doing it? <foo /> xml syntax. meaningful in xml (including xhtml). however, let deal html. how can browser know if tag still needs closed somewhere when that? some elements have required end tags. these must have explicit </foo> some elements cannot have child nodes , must not have explicit </foo> . example

application crashes throwing null pointer exception on line roomlist.getadapter().getcount() . need fetch each edit text value listview , apply computations on it, after searching various posts, have found out solution not working properly. roomlist = (listview) vi.findviewbyid(r.id.list2); (int = 0; < roomlist.getadapter().getcount(); i++) { view view = roomlist.getchildat(i); edittext edit = (edittext) view.findviewbyid(r.id.editroom); log.d("value each edit text", edit.gettext().tostring()); } you have npe because roomlist.getadapter() returns null . maybe didn't call roomlist.setadapter(listadapter adapter) . by way, should change name roomlist roomlist , stick java convention . roomlist.getadapter() @ first glance looks static method call of roomlist class.

im populating hashmap this var temp = ${task.get(i).id}; wf.map[temp]=${task.get(i).isconnected()}; while accessing map, im accessing in way var temp = taskid.value; var connected= this.map[temp]; here, im getting connected undefined. in case, temp = "00000114000000000002" . accessing this.map["00000114000000000002"} gives me same problem. instead if access this.map[00000114000000000002] , works absolutely fine. i tried typecast temp number, int , no luck. how deal issue?
