Ok, I set my extents to:
<map initialExtent="-160300 4684100 1165200 3843700" fullExtent="-304741 6062980 4501420 3011000">
in config.xml. When the map starts, it goes to an area that there is obviously no data - just a dark screen. If I click on my old bookmarks, then the overview map zooms to the correct OLD area (in Lat/Lon), the overview map then shows map parts, and when zoomed out enough, the map shows data from the StreetMap layer, but not mine. So, something here is still not correct.
Is it something to do with the wrong extents? If so, what would make it right? And further, what needs to be done to have the overview map show the correct extents too, when things work the way they are supposed to?
Still workin...
