RE: Removing nested bean collections in session scope.......
I have had this issue before. In your next action, remove mapping to the ActionForm in your struts-config.xml. -Original Message- From: Al Willingham [mailto:[EMAIL PROTECTED] Sent: April 3, 2003 12:47 PM To: [EMAIL PROTECTED] Cc: [EMAIL PROTECTED] Subject: Removing nested bean collections in session scope... Hi, Thanks for considering this... I'm really stumped. I have several layers of collections, ie, a nest of beans inside a nested bean in an actionForm with session scope. When I am finished with the collections, I call my own reset method and set the top level collection to null. I am not overriding the default reset. I assume that if I set the top level collection to null, that there is no longer a reference to the other nested collections and they are garbage collected. When I re-use the actionForm within the same session, the collections that were nested are still in session scope and reappear. But, the collection that I set to null is null. I am sure I am getting the correct session bean because I check for an attribute with a unique value before and after I call my reset. I would really appreciate any insight or suggestions.

RE: Removing nested bean collections in session scope.......
If I remove the mapping to my actionForm, I get an error indicating that my jsp cannot retrieve definition for form bean null. Do I need to usebean scope = session?? My mappings are: First Mapping.. Second Mapping Changed second mapping to. On Thu, 2003-04-03 at 10:24, apachep2 wrote: > I have had this issue before.

re: Removing nested bean collections in session scope.......
It sounds like the ActionForm is in session scope (the default) and that
there is a reference to the other collections on the ActionForm.
You may also need to dispose the ActionForm after resetting the
collection, something like
request.getSession().set("myActionForm",null);
