1. Create new polygonal layer.

2. Create new polygon

3. Add ring (see attachment)

4. Using "Reshape Features" tools cut the ring (see attachment)

At result we have non identifiable ring.

Actually I noticed that the vector layer behaves differently if it is postgis/spatialite or if is a shapefile.

After reshaping, the ring becomes a "part" (an island), then:

*) in postgis/spatialite the island is not selectable nor identifiable. If you use the "select features" tool on the main polygon then it then selects also the island. The identify tool doesn't work the same, as identifying the main polygon do not highlight the island.

*) with shapefiles the resulting island is both selectable and identifiable but only after saving the changes. Before saving changes the island in not identifiable nor selectable, as in the above case.

By the way, is correct the ring become an island after reshaping the polygon?
