"Object not in form" is most often caused by attempting to refer to an
object in the "current form" without verifying what form that actually is.
If I remember correctly, a listbox actually is a form, so if the current
form is the listbox and your code attempts to get a pointer to the listbox
by referring to an object index in the current form, then it will fail.
The safe way to get a pointer to an object on a form (MainForm, for example)
is to use
FormPtr frmP = FrmGetFormPtr( MainForm );
instead of
FormPtr frmP = FrmGetActiveForm();
Then you can use
ObjectType *objectP = FrmGetObjectPtr( frmP, FrmGetObjectIndex( frmP,
YourObjectID ) );
