[ http://issues.apache.org/jira/browse/FOR-672?page=all ]
Ross Gardler updated FOR-672:
-----------------------------
Priority: Trivial (was: Blocker)
The specific problem in the voice plugin has been resolved (thanks Thorsten)
however, the underlying issue still remains. I'm reducing the priority to
trivial, but leaving it open as this is a very confusin error message and
having this in here may help others coming across the problem.
Sooner or later the problem will be removed as views mature and become
independant of the old skinning system.
