Re: Problem with pluto 1.1

I'm guessing that you're having class loader issues.  The portlet 
request which is being dispatched to process your request is not being 
correctly cast into the RenderRequestImpl which is needed.  This can 
happen if you have two version of the pluto container jar in your classpath.

The only version should be the one in common/lib.  Can you make sure 
that there's not another version either in the pluto portal war, the 
testsuite war, or another classloader path.

Thanks,
