Hi @ all,
I'm currently working on the JBoss Portal where i have one portlet in
which i want to use the dataScroller from tomahawk.
I have real looks great sometimes, but the most time I'm getting one
exception (duplicated ids in the faces tree - original part of the
exception is at the end of the mail). I have already tried to declare
fix ids, but it doesn't matter.
my environment:
JBoss AS 4.0.4.GA
JBoss Portal 2.4
JDK 1.5.0_08
MyFaces 1.1.5-SNAPSHOT
Tomahawk 1.1.5-SNAPSHOT
Any advice would be helpful ...
Thanks,
Stefan
