Docking / Prism integration with Serialization

Hi Ross,

Sorry without a repro, it's hard to say.  Note that you also can download our full Prism add-on source code from our Codeplex project.  You first may want to grab that and debug into it.  If you think it's a problem there then send us the sample you have.

If you send our support address the sample project, be sure to rename the .zip file extension so it doesn't get spam blocked.  Or if it's a couple lines of code change, just tell us what the change is.  For anything more complex, the full sample would be better.  Thanks!

I'm having the exact same problem. It happens when I have a tool windows already open and I call LoadFromFile. It throws the same exception. 

If no tool windows are open, then it works. 

Is this an issue with the actipro dock or the prism interop?

Thanks

I am experiencing the same thing. I don't use Prism integration, though the exception is the same. I use LoadFromString. We followed the example from the sample browser, and think it was close to the sample. Another member of the team implemented this part of the functionality.

I don't know if you integrate with MVVM pattern for loading the toolwindows/documentwindows. If you do, try using DeferredObservableCollection as your ToolwindowItemsSource, and use BeginUpdate/EndUpdate after populating your items. At least for me, I haven't been able to reproduce the exception since I started calling those methods.

Hi, we never received a sample project so it's hard to say.  Or as mentioned above you could debug with our Codeplex project to try and see where the problem might be.  Please let us know what you find if you try that, or you can send us a sample per ths instructions above.  Thanks!
