Hi,
I had some issues trying to load different raddock's layouts containing distinct numbers of Tabbed Documents. This error always occurs on as specific situation, I'm gonna explain considering this two layouts:
LAYOUT1 = 4 Tabbed Documents
LAYOUT2 = 3 Tabbed Documents

First I load LAYOUT1 on my raddock and it creates 4 new Documents without errors. Then I load LAYOUT2 and apparently raddock re-use 3 opened documents and dispose one, that's ok. Finally, when I try to load LAYOUT1 again, I get a disposed object exception as below. I simulated this situation on Q2 2013 SP1 Examples (Dock\Serialization) and got same error (this example only uses ToolWindows, but when you dock the control filling the parent it becomes a Tabbed Document property). I really need that funcionality to by your product, thanks for your attention.

Hello Vipper,

Thank you for contacting Telerik Support.

I confirm that this is an issue with our RadDock when loading/saving layout. I have logged it in our Public Issue Tracking System - PITS. You can track its progress, subscribe for status changes and add your vote/comment to it on the following link - PITS issue.

I have also updated your Telerik points

Currently, the possible workaround that I can propose is to remove all document windows in the RadDock before loading the layout:
radDock1.RemoveAllDocumentWindows();
radDock1.LoadFromXml(@"..\\..\\..\\layout1.xml");

I hope this information helps. Should you have further questions, I would be glad to help.

Regards,
Desislava

Hi,

I'm also experiencing a similar issue. I would like to see the details of the PITS issue you linked, but that link doesn't get me to it. Perhaps the link is dead? Could you send me a link that would provide the details on the issue as well as it's status. I'd like to know if this has been fixed, and if so, in what release.

The workaround here did not help us with out issue.

Thank you,
Denis
