Class Cast Exceptionin Views processing
---------------------------------------
Key: FOR-672
URL: http://issues.apache.org/jira/browse/FOR-672
Project: Forrest
Type: Bug
Components: Views
Reporter: Ross Gardler
Priority: Blocker
Fix For: 0.8-dev
I've seen this before with views, but the problem "just disappeared" whilst I
was exploring it. I have no idea why.
Here's what I did:
1) Modified voice plugin to work with views (committed to svn now).
2) did forrest run - page rendered but content was missing (mini toc and title
were present though)
3) svn up
4) build clean
5) build
6) deployed views plugins with views.sh
7) forrest run

I've not got time to do further investigation just now, can anyone reproduce
this (perhaps using the voice plugin)
