Then maybe there is something wrong with your projection file? Can you post your EPSG26986.js, your context and your config xml files? http://demo.communitymapbuilder.org/demo/mapbuilder/demo/basic/index.html?bbox=-180,-90,90,180 > doesn't get exactly as > http://demo.communitymapbuilder.org/demo/mapbuilder/demo/basic/index.html. And what about [1]? Because this is the original extent of the map (lower left lon, lower left lat, upper right lon, upper right lat) > And when you mouse over the map of http://demo.communitymapbuilder.org/demo/mapbuilder/demo/basic/index.html?bbox=0,0,50,50 > (0,0) and (50, 50) doesn't seems to be the bounding box of the map. > > I know openlayer map image expand 1/2 to both North, West, South, East for > the purpose of tiling/catching. But this doesn't seems like the reason. It is the reason. 0,0,50,50 is a portrait oriented rectangle, while the map is landscape oriented. And Mapbuilder zooms exactly to the next valid resolution, which will be larger to the north and south than the bbox. The behaviour of Mapbuilder is correct. If you really need to zoom to an arbitrary extent, you can build a custom widget that uses an OpenLayers hack as described in [2]. Regards, Andreas.
