[Users] How to share actions between multiple layers?

[Adam Ratcliffe]

Yes I'm using the DrawFeature and ModifyFeature controls.  Only 1 layer needs to be edited at a time so that's fine.

What I'm unsure about is how to deal with the one-to-one relationship between a GeoExt.Action, an OpenLayers.Control and the layer referenced by the control.  I was thinking that I'd probably need to do something like create a set of action instances for each layer and when a layer is selected in the map legend remove the set of existing toolbar layer actions and add the actions for the selected layer.

Does this sound like a reasonable approach or is there a better way?

Cheers
Adam

Each of these actions wraps an OL control that has a reference to a single layer.  How would I go about creating actions that can be shared by multiple layers?
