Subject Re: [struts 2] Two forms for one action
Date Wed, 14 May 2008 17:32:32 GMT
The action class does not have state information. Each request is handled by
a different object. If there are appropriate form input fields in the jsp,
struts params interceptor will call the getters and setters on form submit,
calling constructors and instantiating new objects for action fields if they
have not already been created. This can create illusion of persistence of
objects themselves.

As for storing information in two forms; two forms can store different
information, and set it into the action when they are submitted. But you
should remember that you can only submit one of the forms at a time.
Normally this means that you can't use the information in the other any more
as a new page is loaded.
