[Users] BaseMap Definition in GeoExplorer

[ELKHATTABI Imane]

Thank you Christian for replying ,

Using JS console , I got these bugs :

1- OpenLayers.js: 1052     ->  Uncaught TypeError: Cannot read property '0'
of undefined

Line 1052 containing the error  :


 return
newBounds;},CLASS_NAME:"OpenLayers.Bounds"});OpenLayers.Bounds.fromString=function(str){var
bounds=str.split(",");return
OpenLayers.Bounds.fromArray(bounds);};OpenLayers.Bounds.fromArray=function(bbox){return
new
OpenLayers.Bounds(parseFloat(bbox[0]),parseFloat(bbox[1]),parseFloat(bbox[2]),parseFloat(bbox[3]));};OpenLayers.Bounds.fromSize=function(size){return
new
OpenLayers.Bounds(0,size.h,size.w,0);};OpenLayers.Bounds.oppositeQuadrant=function(quadrant){var
opp="";opp+=(quadrant.charAt(0)=='t')?'b':'t';opp+=(quadrant.charAt(1)=='l')?'r':'l';return
opp;};OpenLayers.Lang={code:null,defaultCode:"en",getCode:function(){if(!OpenLayers.Lang.code){OpenLayers.Lang.setCode();}


2- GET http://localhost:8080/myapp/openlayers/lib/img/blank.gif 404
(Introuvable)

When I deleted the  'Global Imagery base map' and set my wms layer  in this
case as a base map  .it works fine.
However , as you mentioned OSM requiers EPSG:900913 , but my wms layers are
set in EPSG:4326.

Using the same structure  definition of the basemap layer in the code above
 (in  GeoExlporer.js) , Is there a way to reproject all the layers to 4326
and still work with OSM?

Thanks in advance
