Werner Punz resolved MYFACES-2742.
----------------------------------

    Fix Version/s: 2.0.1-SNAPSHOT
       Resolution: Fixed

Ok it is fixed, the event handler now is passed down properly, sorry for introducing this bug, I tried to eliminate all bugs upfront, since the entire refactoring process was more or less a rewrite of 50% of the codebase, but I missed this sidebhavior which triggered the bug. I hope it was the only one I introduced in the codebase.

Nevertheless, the refactoring was needed to get the codebase into a cleaner state for future extensions.
Again sorry for this.

> Request parameter "javax.faces.behavior.event" has undefined value if we submit button by ajax. The server side code isn't able to recognise that the button is submitted.
> If we have xhtml like this:
> <h:form prependId="false">
>      <h:commandButton id="buttonId">
>           <f:ajax />
>      </h:commandButton>
> </h:form>
> the commandButton is rendered to this html output
> <input type="submit"
>     onclick="jsf.util.chain(document.getElementById('buttonId'), event,'jsf.ajax.request(\'buttonId\',event,{\'javax.faces.behavior.event\':\'action\'})'); return false;"
>     name="buttonId"
>     id="buttonId">
> When we submit the commandButton, javascript is performed and post parameters contain "undefined" value for key "javax.faces.behavior.event". I think that problem is in _Runtime.js in method exists. The method has two arguments root which is an array and subNms. In our case root contains
> execute :  '@this', render : '@this', javax.faces.behavior.event : 'action' and subNms is "javax.faces.behavior.event". Next part of code tries to split subNms by dots. These parts are looked up in the root but the root contains whole key "javax.faces.behavior.event". The method returns false and the request parameter "javax.faces.behavior.event" stays undefined.
