> ajax event listener looses 'source' in 'success' event
> ------------------------------------------------------
>
> Key: MYFACES-4712
> URL: https://issues.apache.org/jira/browse/MYFACES-4712
> Project: MyFaces Core
> Issue Type: Bug
> Components: General
> Affects Versions: 4.0.2
> Reporter: Milo van der Zee
> Assignee: Werner Punz
> Priority: Major
>
> I'm adding an event listener for the ajax events. I do this by calling
> `faces.ajax.addOnEvent(onEventFunction)` and I expect all forwarded events to
> have the 'source' value set to the original source that triggered the ajax
> flow. But this does not seem to work when switching to a different page. It
> works fine when the view stays on the same page.
> This used to work in 2.3.x versions and is needed by RichFaces.
> See [https://github.com/MilovdZee/myfaces-minimal-test] for an example of
> this behaviour.
> {code:java}
> function onEventFunction(data) {
> console.log(data);
> }
> faces.ajax.addOnEvent(onEventFunction);{code}
> And then in the xhtml of page 1:
> {code:java}
> <h:commandLink id="button" value="to page 2"
> action="#{pageSwitcherBean.toPage2()}">
> <f:ajax/>
> </h:commandLink> {code}
> A plain commandbutton has no issue and the source is preserved in all
> statusses:
> {code:java}
> <h:commandButton id="button2" value="delay"
> actionListener="#{pageSwitcherBean.toPage2()}">
> <f:ajax/>
> </h:commandButton> {code}
>
> My expectation is that this has to do with the render of the elements. The
> source dom element disappears due to the fresh rendering of the page.
> And this also means that it does not sound that weird that the source is
> null. The element is gone anyway and so the meaning is minimal. But it very
> much looks like it used to be there.
> For reference I also added the same functionality with myfaces 2.3.11. With
> 2.3.11 everything works as expected. The source is also available in the
> SUCCESS event.
