MyFaces-Orchestra-ViewController : NullpointerException

Hello,

      currently I am using Orchestra in Portlet Environment and faced with
ViewController exception:

java.lang.NullPointerException

      Any solution?

Hi Mario,

just shooting into the dark: do you have a phase-listener registered
before restore-view for Orchestra? This phase-listener will not be
called in the portlet-case if only rendering is executed.

regards,

Martin

I know that the portlet-bridge folks were talking about a simple demo
app. Not sure if there is already something like that.

Seems like the same problem as in your other thread.

Looks like I have to setup a protlet environment to debug things.
It would be so helpful if you could provide a simple webapp to not have
to setup all this by myself. Any chance? Else it might take some time as
next week are holidays here and I am not sure if I manage to get enough
free time and a good enough internet connection to being able to work on
this.

Ciao,
Mario
