Hi,

I have a Form 1 that has a couple of BIZ objects referenced in the Form 1 properties (e.g. thisform.my_biz_obj)

In a click method of a button (on Form 1) Form 2 is instantiated and the BIZ object references are passed to Form 2. In the INIT of Form 2 the BIZ objects are assigned to properties of Form 2 (e.g. the same name as in Form 1, thisform.my_biz_obj).

My question is, when Form 2 is released should I destroy the references of the BIZ objects? My concern is that if I set the property thisform.my_biz_obj of Form 2 to NULL it will destroy the BIZ object for Form 1 (which is not what I want). By the same token I don't want to end up with dangling references.

TIA for your help.
