java - JSF / RichFaces - How to call programatically an ActionEvent from HtmlAjaxSupport (a4j:support) -


i'm doing this

htmlajaxsupport.setactionexpression(createmethodexpression(                         "#{questionariomb.visualizarquestoesfilhos}", null,                         new class[0]));

the method 

public void visualizarquestoesfilhos()

is called.

but want call

 public void visualizarquestoesfilhos(actionevent event)

because way, can component being clicked.

what need set in htmlajaxsupport work?

create actionlistener expression in jsf 1.2 or newer:

facescontext context = facescontext.getcurrentinstance(); methodexpression actionlistener = context.getapplication().getexpressionfactory()     .createmethodexpression(context.getelcontext(), "#{bean.actionlistener}", null, new class[] {actionevent.class}); uicommandcomponent.addactionlistener(new methodexpressionactionlistener(actionlistener));

to avoid lot of boilerplate code, can wrap nicely in helper methods (if necessary in helper/utility class), e.g.:

public static methodexpression createaction(string actionexpression, class<?> returntype) {     facescontext context = facescontext.getcurrentinstance();     return context.getapplication().getexpressionfactory()         .createmethodexpression(context.getelcontext(), actionexpression, returntype, new class[0]); }  public static methodexpressionactionlistener createactionlistener(string actionlistenerexpression) {     facescontext context = facescontext.getcurrentinstance();     return new methodexpressionactionlistener(context.getapplication().getexpressionfactory()         .createmethodexpression(context.getelcontext(), actionlistenerexpression, null, new class[] {actionevent.class})); }

java - IntelliJ - No such instance method -

using intellij's 12 ultimate, i'm running following code in debugger: java import play.api.libs.json.jsvalue; public class foo { ... public jsvalue tojson() { ... } public class fooexample { ... foo foo = new foo(); system.out.println("...); //<-- breakpoint at breakpoint, right-clicked source code , picked "evaluate expression," typing in: foo.tojson() . but following error showed up: no such instance method: play.api.libs.json.jsvalue$class.com.foo.foo.tojson () am doing wrong? foo#tojson calls scala code, if matters. edit had breakpoint after instantiation of foo. downvoted it, deserved it. edit my answer no longer valid after op modified question (i.e. moved breakpoint actual is).. a breakpoint hit before line executed. in case foo has not yet been declared or instantiated (i.e. foo constructor has not yet been called). you'll need put breakpoint @ next line (or step on current line) if want evaluate foo .

i wondering if html5 element can have 2 ids, this: <button id="thing1" id="thing2" name="button1" onclick="change()">click here</button> or this: <button id="thing1, thing2" name="button1" onclick="change()">click here</button> also, if 1 of ids said 1 thing, , other id said thing, 1 used? tl;dr : no. in versions of html, each element can have 1 id. see the spec : the id attribute specifies element's unique identifier (id). [dom] the value must unique amongst ids in element's home subtree , must contain @ least 1 character. the value must not contain space characters. note: there no other restrictions on form id can take; in particular, ids can consist of digits, start digit, start underscore, consist of punctuation , etc. note: element's unique identifier can used variety of purposes, notably way link specific parts of document usin
