This might be a rounding issue. I encountered a similar issue related to WMC a while ago, and the fix was to keep a better precision when parsing floats. ( http://trac.openlayers.org/ticket/2242 ) You can try to set the default precision to 18 for example, instead of 14, or set it to 0 so that the original non-truncating behavior of OpenLayers <2.8 is preserved.
OpenLayers.Util.DEFAULT_PRECISION = 18; Cheers, Bruno On 16 August 2010 21:10, Alexei Peters <apet...@fargeo.com> wrote: > Hey everyone, > > For a project we're working on a user can save a map (extents, wms layers, > vectors, etc) and then come back during a later session and reload that map. > > But we've noticed a small bug/feature in OL concerning the saving and > reloading of map extents. > > If you run this in Firebug you'll see what I mean: > > blah = map.getExtent(); > map.zoomToExtent(blah); > > Most of the time it seems when running the above code the map will zoom out > one step from what is currently displayed on the screen.
