OpenLayers DrawFeature undo() and redo() functions

Question

I need to implement undo and redo functions in my app. I found that the simpliest way(?) is to use openlayers undo and redo build-in functions. -> http://dev.openlayers.org/docs/files/OpenLayers/Control/DrawFeature-js.html

But I have troubles with implementing them. Can anybody provide me with an example of their implementation(OpenLayers.Control.DrawFeature.undo) or give advice how can I implement undo and redo functions in another way?

Answer 1

Have you take a look at its corresponding example?

See Undo/Redo Drawing example.
