    I have an entity Plant that has a collection of Lines and Lines has a collection of Stations.  I bind my tree to an ObservableCollection<Plant> then each level of the heirarchy binds to the EntityCollection of Lines and then Stations.
    When I add a new Line or new Station everything looks great until I save, when the save is completed my new items are suddenly disabled in the tree.  I have a hack in place right now to reverse this, but I'd love to know why they go disabled and how to properly fix it.

    I'm using RIA Services as the backing WCF service.

    Hi Dan,

    It's hard to say what the reason may be without taking a look at your code. We are not aware of anything in the TreeView that will cause an item to be disabled after the operation you describe. Can you provide a sample project that demonstrates the issue?

    All the best,
