Hack: Moving data-aware components at run-time to other forms

My application requires letting the user move an entire panel with
data-aware components from one TForm to another - at run-time.

I found this is possible by changing the components parent property,
and everything just pops over.

However, a slight hickup is that the components may need to be moved
back. Coding this causes the compiler to say "Unknown identifier".
Fair enough, the components aren't there yet.

Anybody got a hack for this?

Email appreciated. I respond to every email.
