In the palm OS documentation they state that if you dynamically add form objects that you must save the new FormType returned from the call because the form may have actually moved in memory. My question is, does this invalidate any pointers to form objects that you might be storing? My guess is yes because of the bug I am seeing in my code.
Here is the scenario. I have a form with a list on it. I attached a POL::CSimpleListCtl to it. I then dynamically add a button to the form which changes the form pointer. When I go to re-access the list via GetSelection(), I get weird results such as the wrong selection index or it crashes. I think the issue is due to the fact that when I attach the list control, POL is saving the ListPtr returned from the form when attach was originally called and now the saved list pointer is no longer valid. The problem is that I am adding the dynamic button from a base class and I have no idea what objects are attached on the current form. It would seem that POL should only store the form pointer and then call FrmGetObjectPtr when ever it needs to access an object on it. Has anyone else run in to this problem or are my assumptions incorrect?
