[Users] TreePanel control doesn't seem to be updating layers when I move them

Hi,

you have to use a GeoExt.tree.LayerContainer for DD support, not an Ext.tree.TreeNode root with manually added LayerNodes.

Andreas.

I have tried experimenting by moving layers up and down (using drag and drop) but it does not seem to have any effect. Am I missing some extra code to make this possible? Thanks for advice.
