InitialPosition="FloatingDockable" - Object reference not set to an instance of an object

[BB]

Hi, using latest WPF controls (2013.1.220.40), when I paste in an example directly from the examples demo (First look for the Docking panel), I get the following error:

Object reference not set to an instance of an object.

If I change the Initial position of the control to DockLeft (or anything other than floating), the demo works. 

Is there a bug in the latest dlls ?

thanks!

Hi,

Unfortunately, we did not manage to reproduce the issue.

Please, take a look at the attached project. For the sample we used the xaml code (without styling and RadPane content) from the RadDocking First Look example and under dll version 2013.1.220.40 it works as expected.

All the best, Alek
