Node will be disappear after change diagram control parent

Hi,

I have a case to move a diagram to a new window, and move back after close the window. (Keep the instance)

And there a problem that the node will disappear after move back.
The problem only haappen when the diagram’s original parent control is host in a tab control.

Dll Version: 2.2.2.4

Have you set http://goxam.com/2.2/helpWPF/webframe.html#Northwoods.GoWPF~Northwoods.GoXam.Diagram~UnloadingClearsPartManager.html to false?

What kind of tab control are you using?

I will use the System.Windows.Controls.TabControl.

UnloadingClearsPartManager Property is work for me.

Thank you so much.
