Hi

I'm using one FormBean and one Action for 2 pages.
Page A calls page B and page B can call page A. It works fine, but I have to place the fields of the other site as hidden fields in the JSP.
If I do not place the fileds as hidden fields, so the fields are initialized thru the reset method.

Now my question: In wich cases will the reset method be called ???
Can I prevent the call of the reset method ?

Thanks

Georg

Here are a few basic comments about how it works:

1) The reset method is called on the ActionForm for every ActionMapping that is performed.
2) The reset method can not be avoided (without tweaking the framework itself).
3) You can choose to reset only certain fields in the reset method.
4) If the ActionForm is in request scope, the reset method doesn't matter a whole lot because a new instance of ActionForm is created for each request from a user anyway.

You did not mention what scope the ActionForm is in - request or session?
If request - you will need to either keep using hidden fields or store the values somewhere in session.
If session - stop using hidden fields and stop resetting the fields in the reset method.
