[OpenLayers-Dev] Layers into Groups

[Jachym Cepicky]

Hi,

sorry, I do not see your point: I want the layers grouped in
LayerSwitcher. The simplest way how to do it, is to specify the group
name
  group: "Group"
and using Group hierarchy
  group: "Parent/Child"

everything happens while new OpenLayers.Layer.* is defined
