The loader's createNode method is the one exposed to the API, and this is what you should override. See http://www.extjs.com/deploy/dev/docs/?class=Ext.tree.TreeLoader and look for the createNode method for an example.

Your solution is indeed better. Thanks Andreas.

One issue is that createNode receives a layer as opposed to a layer
record, so when overriding createNode one will need to find the layer
record corresponding to the layer. We could change the code so
createNode receives a layer record. We could also change LayerNode so
it can be configured with a layer record; currently the "layer" option
can reference a layer or a layer name, so we could extend this so it
can also reference a layer record.
