Thank's Mark !
It solved the problem.

I saw in your code that its necessary to insert THIS.INIT() in the AutoOpen, with this I discovered that the sequence of events in CA is not the same if I have the code of the Init event writen by the VFP Builder, and if the CA used is based in a class like yours.
I belived that if the CA Init event is readed first with all the properties by VFP when created by VFP builder the same would happen with a CA class, but now I know it's not this way it happens.
I just cant understand this behavior.

Thanks again.
