You just need to create a duplicate of the layer with the word UNLOCKED at the start. For example, if you have a layer called property in the mxd, arcims or wms you would create another called UNLOCKEDproperty. There is no need to add the unlocked layer to the toc modemodel. When the user right clicks the layer, Weave checks to see if this layer is available in the mapengine. Iif If it is, the Unlock Layer menu item will be enabled.
