There is a problem with the OnEndDocking event of a DockPanel :
The Zone Parameter always is nil
Details:
This Problem can easily be seen in TdxCustomDockControl.EndDocking():
The Object-Variable (DockingTargetZone) is cleared and in the End of the Method DoEndDocking()
uses DockingTargetZone as a Parameter for the Event (which always will be nil)
Thanks

The Zone parameter is always initialized with nil in the OnEndDocking event raised for dock panels
