Matthias Weßendorf commented on TRINIDAD-1879:
----------------------------------------------
Hi,
just tried with Trinidad trunk and myfaces trunk.
The demo for "tr:commandButton" uses the action outcome to navigate to another
demo page.
That worked fine, here.
Can you give me a test-case for this problem?
Or can you try with latest greatest Trinidad/MyFaces on your side?
