Save frame status

[sonjli]

(Sorry for possible duplicate post. I can't find the original one in forum... )
Hello,

I use an application model like the "AsyncRenderFrame" demo.
Only one frame is active, the previous is detroyed.

Where do I save the previous frame state if I need to reopen it?
I mean: checkboxes, radios, edits, dataset cursors, etc.

Now I use the "session.clipboard" system as a memory kv store for this purpose, but I am not sure if it is a good choice.

Thanks,
Eddy
