[Users] How to register different "dblclick" listener on BaseLayerContainer and OverlayLayerContainer

[Andreas Hocevar]

I just confirmed that this doesn't work. But using the tree.js
example, I also confirmed that a different approach works:

--- examples/tree.js	(revision 2656)
+++ examples/tree.js	(working copy)
@@ -166,6 +166,9 @@
         listeners: {
             "radiochange": function(node){
                 alert(node.layer.name + " is now the the active layer.");
+            },
+            "added": function(node) {
+                node.on("dblclick", function() {alert("dblclick");})
             }
         },
         rootVisible: false,

Regards,
Andreas.
