AW: O$ 5: $methodtext.$assign throws error 25216 (attempt to use instance/task var…)

Hi Nick,

Are you sure the $cwind is correct in your context?
Could it be, that you ought to be using $cinst instead of $cwind?

Hi Peter,

Thank you for testing this out yourself.

I don’t think the problem is with the Item Reference variable.
When I test the code in a new window class, I’m not getting any errors either. It’s only when I set the superclass that the error appears. So I’m guessing the problem lies somewhere in the $control method of my window superclass.

I’ll do some further digging.

Cheers,

Nick
