Ken Finnigan commented on GTNPORTAL-2479:
-----------------------------------------

I get an "Uncaught #<Object>" Exception when RichFaces is trying to load the response from the server.

The full JS call stack is:

Uncaught #<Object>

I've looked at Array.each in Util.js and it doesn't appear to have changed since GateIn 3.2, so not sure why the error is manifesting there.

For reference, the anonymous function at the top of the stack, which gets the exception, is part of Enumerable.detect which I've reproduced below:

{code:JavaScript}
  detect: function(iterator, context) {
    var result;
    this.each(function(value, index) {
      if (iterator.call(context, value, index)) {
        result = value;
        throw $break;
      }
    });
    return result;
  },
{code}

The exception appears to occur when "throw $break;" is called.

I'm no JS expert, so a little unsure of where to go from here.

>          Issue Type: Bug
>      Security Level: Public(Everyone can see) 
>    Affects Versions: 3.3.0.Final
>         Environment: GateIn 3.3 on AS5 or AS7, with JSF and RichFaces
>            Reporter: Ken Finnigan
>            Priority: Blocker
>             Fix For: 3.4.0.Final

>
> Deploying a RichFaces/JSF portlet to GateIn, with JBoss PortletBridge, no longer correctly handles Ajax menu navigation.
> In GateIn 3.2 selecting a menu option in the RichFaces demo would redisplay the portlet with new content in the right hand section of the portlet.  In GateIn 3.3 clicking the menu option has no impact, however, refreshing the page then does display the correct content.
> It appears that between GateIn 3.2 and 3.3 there was a change to how Ajax action requests are handled such that it doesn't result in an update to the portal page without an entire page refresh.
