intermittent exception in TilesRequestProcessor

[Alayne Wartell <al...@towers.com>]

Hi,
I'm getting the below exception, but only after hot-deploying a class file
-- for example, an ActionForm-derived class. I believe the error occurs
only on pages that use the particular deployed class.
I just added the Tiles plug-in and configured the TilesRequestProcessor. I
do have a tiles-def.xml which is not being used yet except for a very
simple test page. But no one is currently working with the test page; no
other pages use any Tiles features at all. The exception seems to occur on
any page
I'm running WebLogic 6.1.1 and suspect the problem is server-specific.
Tomcat runs fine. Therefore, I don't expect that anyone will have any ideas
for me; but I'm still hoping.
Thanks.
