Thanks for your reply Stephan,
I have checked your advice, but the result is the same; i also got the
same exception.

Stefan

Hi Stefan,
I often got this, if I modified the jsf-file on the server while it is still
running. Remove the generated java/class files, then it should work. Otherwise
it is somewhere really a bug...

Stephan with 'ph' :-)

Betreff: Problem with duplicated Ids on t:dataScroller component
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
