VFP 9, Class definition is cyclical error

Have a container-class which contains two custom-class pageframes, one is
placed on the others page.

inputctrl1 <or one of its members>. Parent : Error loading file - record
number 1976. FWPAGEFRAME_B1 <or one of its members>. Parent : Cannot add
FWPAGEFRAME_B1. Class definition is cyclical

This error occurs when running the application, not during class editing.
With only one instance of the pageframe class in the container-class the
application runs fine. It also works if the second pageframe is not placed
on the other pageframe's page.

As far as I can tell this does not match:
"You have attempted to specify a class in an ADD OBJECT statement whose
class definition is the same as the class being defined. "

Any idea's ?

TIA

So you have a custom pageframe class and you are putting one instance
of this pageframe into the page of another instance of it? I have
done this many times, so that would not cause the error. There must
be something else involved besides that.

Hi Tim

Thx for the feedback.

One posible reason for the problem could be that I'm using a custom-page
class - will look into that later on. VFP 9 seems to have some trouble with
this. But for now, the problem was simply solved by using another pageframe
class.

Ahh... I have not tried this with a custom page class. Just
with a custom pageframe class in VFP6, 7, and 8. Haven't done
anything like that in 9 yet.
