design question

[dirk]

I have 3 FormObjects.
I have a newuser.jsp page containing the form userForm, in this form i put a 
javascript button with an onclick event, window.open with a popup (adresuser.jsp), 
with the form adresUserForm.  Finally i have on the userForm another javascript button 
with a popup to specialinfo.jsp. This page contains the specialInfoForm. After closing 
these popups i want to have one action ( submitting the userForm ). How can i get the 
values from the 2 other formObjects ? Is there anybody that has a similar problem ... 
Thanks !
