    Hi Armin,

    it works fine! That’s really great, thank you!

    But I have another problem with using the TabContainer. If I’m just binding to a collection and then removed a TabContainerItem, I can’t add one anymore. I suspect it’s due to the lack of management of the TabContainer’s indices. I get the error message attached.

    I’m using the client-side BO attached to manage the collection.

    If I want to use the methods from the API reference instead, like addItem or insertItem, it doesn’t seem to harmonize with the binding anymore. Here is the link to the API:

    How must it be implemented correctly?
