[Users] Remove layers from outside (not within a layertreepanel)

[Christian Mayer]

Hi,

I just tested your code and modified a bit

Ext.each(mapPanel.map.layers, function(layer) {
      if ((layer)&&(!layer.isBaseLayer)){
           mapPanel.map.removeLayer(layer);
      }
});

In my case this works well.

Best regards,
Chris
