Hi

I have a window with a docking panel. I save the layout when I close the window. It works well, but if I undock a panel then loadlayout raise the following exception (I attached the xml layout file too)

Hello Gianluca,

I have prepared a sample project using the provided RadDocking layout, in order to get as close as possible to your current project scenario, however, I was not able to observe the specified exception. With that said, would it be possible for you to try the provided sample project, and let me know if I am missing something?

No answers yet. Maybe you can help?
