submitted a form?

Thanks for the reply Chuck.

The action I am calling is the first action after the form has been filled
in and the user submits the form.  All
the data should still be in the form.  I can access all the other variables
in this ActionForm which are of type String, so
I find it strange that the Vectors have become null.  
Any ideas? 


Cheers

Tony

action that is being called is configured as request scope and not session
in the Struts configuration file. Therefore, after the HTML page is drawn
(using the Vectors to populate the drop-down boxes), the ActionForm is
recycled because the request is complete. If you need data like this to
stick around and not have to get it again from your database or backend,
then you either going to have to make the action session scope, or hide the
data in the page. Take a look at the ActionMapping defined for the action
being called and see if it doesn't have something like scope="request".
Actually, I think the default is request, so if you don't have a line
scope="request" in the mapping, it will default to request scope.
