Do a edit like moving a node or moving a feature, then move it again in order to get 3 statuses in the undo/redo panel, the initial state and the two editing operations. Now try to get back the first editing operation, instead it will show the layer from the original status.

I can't reproduce this anymore - can you?

  • Description updated (diff)

I just tried on master from osgeo4w and still can see what is described in the ticket. Used a polygon shapefile for tests.

One thing I notice now:

  • if you use the undo/redo panel to move from

initial state (called "empty" in the panel) > second state > third state

then is all ok

  • * if you use the undo/redo panel to move from

third state > second state

then when clicking on second state it shows the "empty" state instead.
