I tried to extend TreeNodeBase (new class MyTreeNodeBase). But now, when I want to use this.clickedNode in the action method, I can naturally only use the attributes which are defined in the interface TreeNode. And because my clickedNode is of type TreeNode, I can't use the new attributes. Can I just use MyTreeNodeBase as the type for clickedNode or what is the best solution for this? Kind regards, Wiebke
