Portlet IPC

gareth_western Sep 29, 2010 10:30 AM

Hi,

We're trying to create an example of two JSR 286 portlets communicating using portlet events, using the JBoss Portlet Bridge. We followed the documentation and according to the logs the event is being sent and received as expected, however the view of the target portlet does not appear to be restored correctly. For some reason the target (listener) portlet loads the defaultViewId for the source (sender) portlet.

Both portlets are part of the same war, however even when I split them in to separate applications the target portlet still tries to display "source.xhtml" after receiving the event.

Note: the EventNavigationResult returned by my Bridge Event Handler is null, as I just want the portlet to reload the current (default) page for the target portlet (target.xhtml).

Any ideas as to what might be wrong?

I've attached my portlet.xml, web.xml, and faces-config.xml

web.xml 2.7 KB
portlet.xml 2.7 KB
faces-config.xml 1.8 KB

It appears that the problem, when both portlets are part of the same .war file, is that they're sharing the FacesContext, and the _pathInfo and viewId of this context contains the values from my first (source) portlet (i.e. source.xhtml).

Is there some init-param or something that I'm missing, which will enable each portlet to have it's own FacesContext?

I'll now try splitting the portlets into two wars and see what happens with the context.

I have sent both events and PRPs across portlets in the same war. For an example see:

Yeah, I've seen your examples. I'm doing everything as you did, so I think the error must be in one of the WebSphere libraries. Ugh

Oh well. Perhaps it just won't be possible to use the JBoss Portlet Bridge for WebSphere (which is fair enough, since it is not officially supported). I'll poke around the IBM forums, and report back here if I ever make any progress.

That's too bad. If you want to debug it and see what's going facesContext, we will definitely apply your patch.
