Thanks for the answer. I tried it but I get the followin error: "Error loading file record ...: Header1 or one of its members. Parent: Object class is invalid for this container"

I have started with a very simple column class defined in a PRG:

define Class jColumn as Column
    procedure init()
        return doDefault()
    endproc
endDefine

And it does not work. It's even worse if I set the headerClass and headerClassLibrary properties.

Thanks,
Javier.
