Hello, Experts!
I keep on getting this message when I open a customized form extension after upgrading to a preview PU 31 provided by Microsoft. The message is this:
"Some elements have been removed from the base form. The form extension items that were modeled after or inside these removed elements have been relocated to end of the form"
The standard form that I have extended is PriceDiscAdm form. Aside from that, I can no longer see the standard fields from it's grid control. It is only displaying my added customized fields, but this is not how it works before the upgrade.

Does this mean that Microsoft upgraded something from this form, thus this happened?
