TreeListView: InvalidOperationException when perform async update of the items source

An exception is thrown when you try to update the items source of RadTreeListView in an async method.

The following error is observed.
InvalidOperationException: The calling thread cannot access this object because a different thread owns it

To work this around ensure that only the main UI thread updates the item source.

Hello Michel,

This isn't included in the planning for the next release (in the end of the year), but we have moved up its priority based on your feedback. Note that this doesn't necessary mean that we are going to start working on it, but there is a better chance. Stay tuned by following this item. This way you will get notified by email as soon as its status changes.

Is there a possibility to get this one fixed any time soon? Using the Dispatcher has some pretty severe performance penalties so it would be nice to be able to use the BindingOperations.EnableCollectionSynchronization instead.
