[Users] How to share actions between multiple layers?

[Adam Ratcliffe]

In my application I have multiple WFS layers that should be editable by the user.  I have added GeoExt actions to the app toolbar for drawing/editing/removing polygons.  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?

Cheers
