    I have a treeview and implement drag and drop. I noticed that when I set a filter on the datasource, the treeview loses attributes like:


    And the drag and drop stops working.

    See this dojo for an example. Examine the dom to see the attributes are there on the first tree node. Click the "Set Filter" button, and observe the attributes are gone.

    This seems like a bug.. Maybe I'm doing something wrong here?

    Hello Ryan,

    Instantiating widgets in the TreeView is not supported. If you need to work with Drag&Drop in the TreeView, use the dragAndDrop configuration option. You can restrict which items are draggable via a dragstart event handler (see the third example). Any modifications to the DataSource will re-render the TreeView, by design, and remove any custom attributes.
