Hi
I am using DynaAction from struts 1.1 in building a form dynamically.
Say I have a purchase order form where there are multiple line items and
which are being added dynamically.
I have added couple of line items and then after a brief period when i try
to add more line items I get the above error javax.servlet.ServletException:BeanUtils.populate.
This occurs if there is session timeout which if I remove does not give the
above error,but which is not a viable solution.
Is there any way to get rid of this problem.
Looking forward to yours reply.
Thanks in advance
Koushik

You said ::

This occurs if there is session timeout




Please check current session is invalid/valid (timeout) before call this method.

And sometime, you can set session is not expire in DD or in your source code.

i had tried out this option also but its not working.struts straight away calls the BeanUtils.populate method and hence resulting in the exception which i had said about.
