you can turn on the overview map switch in the views area but the resulting map has an empty overview map. I think this requires a layer of its own to show in the overview.....I did not see where I could set the layer for the overview, maybe thats all thats missing to make it work...

more playing on this one shows that not only does the overview come back empty, but it breaks the map too, resulting in the wrong default baselayer....

I think that the overview map is complicated enough that it should be moved from controls to a behavior.

This should be moved to a behavior. I tried playing around with this just to get it working in a basic sense but to no avail, so I am just removing it form the options. Helpful page: http://trac.openlayers.org/wiki/Control/OverviewMap

I think this should be a 2.x feature.

The OverviewMap behavior is a tricky one indeed, and won't work with many common map types (essentially all TMS/OSM 'tiled' map types, because they don't zoom out farther than 0). I don't think that this is an essential thing for a 2.x release, but patches are welcome.

Setting this as by design, because it won't be part of OpenLayers core in the near future, given lacking support from actual maps and the complexity of implementation. Feel free to implement this as an add-on module.

I've created a little module that adds this behavior.
It's been 5 years since this issue was closed. I'd like to put it up for a re-evaluation.

The previous upload was a custom module.
This one is the module refactored as a patch.

There was a small problem with the patch. I've attached both the rerolled correct patch (for rebasing) and the patch against 45b8d61 (fixing the introduced problem).
