In order to resolve the issue I described in the initial post, I have to change how I instantiate MyClass2.
Instead:
thisform.oMyClass2 = NEWOBJECT( "MyClass2", "MyClass2Lib.VCX")
use:
thisform.NewObject( 'oMyClass2', "MyClass2", "MyClass2Lib.VCX")
Thank you, Thierry, for the solution.
My question now. The previous code (above/old approach) I would use Destroy method of the form to set the object oMyClass2 to .NULL.
If I change the code to the .NewObject, should I leave the code in the Destroy method? Or it may cause problems?
UPDATE. The existing code in the DESTROY method
thisform.oMyClass2 = .NULL.
causes error. So I see that I need to comment/remove it.
Which brings me to another question. When the form is released, will it "automatically" destroy the object oMyClass2? Or I may have a "hanging" reference?
