Hello, thank you very much - this was the error - its working now - I setted the scope to "session" ... THANKS A LOT!! But another question - this also means, that the data is stored in the session - so the session-size is growing ... is there another solution, because I think there is data in the session that is only needed for this form - but if the user is doing something other - this data isn´t used any more - but still in the session :-(
kind regards, Hans -----Ursprüngliche Nachricht----- Von: Hubert Rabago [mailto:[EMAIL PROTECTED] Gesendet: Montag, 06.

When Struts processes the submitted form, it will create a new instance of your ActionForm. The question now is, is the new instance ready to deal with setting values on your ArrayList field? Struts will not instantiate that list for you, it wouldn't know how to. So make sure that when Struts accesses your ActionForm, the ArrayList already exists.
