Volodymyr Siedlecki commented on MYFACES-4680:
----------------------------------------------
I'm missing something here – the {{behaviors}} callback should be for the web
socket, not the XHR request.
Let me do some more investigation into this.
> 4.1 TCK Failure: Spec1396IT#testViewScopedWebsocket
> ---------------------------------------------------
>
> Key: MYFACES-4680
> URL: https://issues.apache.org/jira/browse/MYFACES-4680
> Project: MyFaces Core
> Issue Type: Bug
> Affects Versions: 2.2.15, 2.3.10, 2.3-next-M8, 4.0.0, 4.1.0-RC2
> Reporter: Volodymyr Siedlecki
> Assignee: Volodymyr Siedlecki
> Priority: Major
> Attachments: test-faces23-websocket.war
>
>
> The app expects "pushed!" to display when the "push" button is pressed. It
> is not, and the test fails.
> Ajax requests do not occur when they are registered a websocket tag, from
> what I could gather. It seems like the renderAjaxOutput behavior isn't
> registered / called with the faces.push.init script.
> MyFaces generated code (see behavior param (1) – second to last):
> {code:java}
> faces.push.init('j_id_c','/test-faces23-websocket/jakarta.faces.push/view?76379b861759b95fa70c118d2e05d29f','view',function(){document.getElementById('opened').innerHTML='yes';},null,null,null,{renderAjaxOutput:[function(event){myfaces.ab('j_id_c',event,'renderAjaxOutput','','ajaxOutput')}]},true);{code}
> Facelet:

> I test the same TCK app on Mojarra, and it sends out two XHR requests when
> the button is clicked. One for the button click and another for the
> renderAjaxOutput event.
> MyFaces only handles the one XHR for the button click. Neither do I see the
> onMessage invoked, which per the javadoc should trigger the behavior (
> "behavior param: Client behavior functions to be invoked when specific
> message is received.")?
