[Users] Layertreebuilder has issues when layer removed.

[Matt Priour]

Well technically, since the layer is removed via user interaction with the tree, then I find the layer associated with the node, remove it, and then remove the node and remove empty parents. In my project this is all custom code and not part of GeoExt. However, if your using the layertreebuilder user extension and it is removing the layer and node for you and you want to run the remove empty parents logic, then you can run that on the treepanel’s ‘remove’ event.

  You’re right. I wasn’t paying much attention to the actual removal logic there. I was mostly trying to demonstrate the use of cascade and/or eachChild. I used something like that in a project were there were all leaf nodes were always part of a group node.
Just to clarify here. This is in your main code, not in added to Geoext somewhere. So when you remove a layer in your main code (I go mapPanel.map.layers[i].destroy() to remove), you are locating the associated node in the layertree and then executing your code?
