Hi we are using Telerik controls 2011 Q1.

We have an application that has a Docking control, and inside another control that has Docking control.

The parameter AllowUnsafeMode = "true" on both.

When we drag the inner Docking we got next exception:

Exception.Message:

 "The specified Visual is not an ancestor of this Visual."

Exception.CallStack;

There is fix for that?
