The bbox of OpenLayers.Control.GetFeature works in utm when the baselayer is 900913 ie. google/bing/etc) and in long/lat when the baselayer is 4326 (ie. my postgis layers served by mapserver), no matter what overlays them. This is what openlayers says.
So, how can I force bbox to be in long/lat when I use one of my layers over google for example? I do want the bbox being in long/lat rather than 900913 (ie. using baselayer projection). I've read many webs about this but with geoserver, some posts about mapserver say that both EPSG:900913 and EPSG:4326 must be set in METADATA, I changed that and also assigned "srs" and "projection" (with the appropriate expression) in my layers (and in protocols) but with no effect in bbox at all. What else could I try?
Any idea will be appreciated, thanks in advance,
