Cannot add items to HierarchicalCollectionView when parent is a leaf

Hi,

i found the solution myself. You've to extend the HierarchicalData class and override the canHaveChildren function to automatically allow every node to have children.

package {
    import mx.collections.HierarchicalData;

    public class EditableHierarchicalData extends HierarchicalData {
        public function EditableHierarchicalData(value:Object = null) {
            super(value);
        }

        /**
         * Override this method to allow any node to have a children.
         */
        override public function canHaveChildren(node:Object):Boolean {
            return true
        }
    }
}

Bye,

Fritz

PS. I found this solution in an example of ILOG Elixir's OrgChart.
