Hi,
I get below error when I tried to use a ognl expression:
${ognl:mySessionWrapper.hashcode()}
I included t5 contrib and components and ognl 2.6.9 jars before running
application. ${ognl:mySessionWrapper} works fine though..
-----------------
SEVERE: Processing of request failed with uncaught exception: Render queue
error in Expansion[OgnlBinding[mySessionWrapper.hashcode()]]: Method "hashcode"
failed for object [EMAIL PROTECTED]

Thanks in advance,
