Portlet preferences problem
Hi all,
I have got 5 portlets in my application that shares the same class.
Whenever I go to edit mode and return back to view mode I am getting
this warning message.
[org.apache.ojb.broker.core.PersistenceBrokerImpl] WARN: No running tx
found, please only store in context of an PB-transaction, to avoid
side-effects - e.g. when rollback of complex objects
And after some time the application is hanging.
Below is my class file.
Please reply ASAP. It is very urgent.

I get the same error, but I haven't looked into how to fix it yet.
