>You mean you add a class to itself ? In class designer it would cause a cyclic definition (two mirrors looking each other). C1 container would include another C1 which in turn should include C1 including C1 and in turn it should include C1.... and so on, a cyclical definition. But at form level you could do it.

oForm = createobject("Form")
>with oForm
>	.height=400
>	.width=600

Cetin,
Your code is exact my situation. My poblem is that i MUST store the class definition in a VCX. Same form object and MyContainer class stored in a VCX cause the error!
I don't try to define a class based on its own.
I have a container class (like your 'MyContainer'), and in a form derived object (stored in a VCX), I need to create a set of 'MyContainer' instances, but nested inside one another. Exact like your example! I don't have a cyclical definition! The involved container class is defined in a different VCX.
If I try your example in a SCX form, it works. But not in a VCX!
Anyway, you give my an ideea and I think it will work. I'll explain to you later.
