f:ajax component produces an IllegealArgumentException when providing a listener with the correct method signature

[ren-zhijun-oracle]

I have an f:ajax tag with a listener defined (in a composite component). <f:ajax listener="#

{cc.attrs.closeListener}

" render="#

{cc.attrs.onCloseUpdate}

"/>
The listener has the signature: public void actionListener(AjaxBehaviorEvent event). This method is provided as a composite component attribute.

The method AjaxBehaviorListenerImpl.processAjaxBehaviour tries to call the no-Arg version of the listener method. It then catches a MethodNotFoundException and then calls the correct method with the AjaxBehaviorEvent parameter.
The problem is that when calling my method without an argument the NativeMethodAccessorImpl throws a IllegealArgumentException and this Exception is nowhere converted to a MethodNotFoundException.

The interface of java.lang.reflect.Method.invoke allows the IllegealArgumentException to occur, but the javax.el.MethodExpression.invoke does not. I guess somewhere in the chain this should be converted (in el, weld or JSF)? Or the AjaxBehaviorListenerImpl.processAjaxBehavior needs to catch the IllegealArgumentException as well?

To help us can you please provide a test case (small app) which causes this issue (with source)?

I provided a small dummy application which reproduces the issue.
Deploy war on GL 3.1 and go to /ajaxTest and start typing in the input box. The error should appear.

The example consists basically of three files:

• main.xhtml: includes a composite component and sets the attribute to # {actionProvider.ajaxListener}
• ajaxComponent.xhtml: the CC which has an inputtext with an f:ajax that has the listener attribute defined as # {cc.attrs.closeListener}
• ActionProvider: SessionBean wich has the method public void ajaxListener(AjaxBehaviorEvent event)

I hope my application of these stuff is within specification.
