Yes it is supposed to work, and it works very well in Jetspeed.
:( So the problem must be on my side
The jpetstore sample is working, the database seems to work as well.
When clicking on a category, e.g. cat, I get the following exception. I
added the stacktrace and the debug output. Perhaps you can give me a
hint where I can look at to find the bug?
The ActionForm CategoryBean used by the Catalog.jsp seems to be filled in during
the actionRequest and stored in the session. During the subsequent renderRequest
the same CategoryBean *is* retrieved again. So, if the DefineTag is getting a
null
value (from catalogBean .getCategory() or .getProductList()) I suggest debugging
the CategoryBean.viewCategory() method which is invoked by the ActionBean
during the actionRequest. That should retrieve and fill in the required values
from
the database. Then, if that works, debug the getCategory() and getProductList()
method when invoked from the defineTag.
Regards, Ate
Thanks
