Thanks a lot Andreas, I tried "hacking" in a new OpenLayers.Layer.Google();
as the default base map in the MapPaneOL file, and it loaded fine until we
upgraded MapBuilder/OpenLayers now it gives me a JS error saying:
objRef.model.map.getExtent() has no properties
http://10.0.20.23:8080/GlobalView/lib/widget/MapPaneOL.js
Line 527
I also tried putting in these options:
var baseLayerOptions = {
units: units,
projection: proj.srsCode,
maxExtent: maxExtent,
maxResolution: maxResolution, //"auto" if not defined in the
context
minResolution: minResolution,
resolutions: resolutions,
alpha: false, //option for png transparency with
ie6
isBaseLayer: true,
displayOutsideMaxExtent: objRef.displayOutsideMaxExtent,
ratio: 1,
singleTile: true,
transitionEffect: objRef.transitionEffect,
visibility: false,
//moveTo: function(){return true}
minScale: 50000000,
maxScale: 1,
numZoomLevels: 20
};
What I am trying to do is use my standard WMC context with a Google base
map, and this worked in the previous version of MB and OL (In Firefox), does
anyone have experience with doing this or is it even possible?
Thanks in advance!
