Hi Luke,
The problem comes from OpenLayers, an OpenSource project used by mapbuilder to render the map.
When the wms request failed, OpenLayers change the css property of the layer div to pink.
You can modify directly in the file /lib/util/openlayers/OpenLayers.js, and change the property OpenLayers.Util.onImageLoadErrorColor to transparent.
The second solution is to redefine all the function called when request failed to do what you want:
OpenLayers.Util.onImageLoadError=function(){
this._attempts=(this._attempts)?(this._attempts+1):1;
if(this._attempts<=OpenLayers.IMAGE_RELOAD_ATTEMPTS){
this.src=this.src;
}else{
this.style.backgroundColor=OpenLayers.Util.onImageLoadErrorColor;
}
this.style.display="";
}
Regards

I have an web application that makes calls to wms services by means of the
GetCapabilities request. From there the GetCapabilities response is parsed
and changed into an xml document from which
mapbuilder can make a map. A problem that I am running into is that when
the GetCapabilities request gives me layers with a LatLonBoundingBox that
isn't global and I am zoomed into an area that is bigger but still
contains the LatLonBoundingBox, I get a pink tile for the layer. When my
viewport is at that bounding box or within it the image shows fine. I was
wondering why this was happening and if there was a way to change it so it
just overlays the image on the map where the data exists rather than a
pink tile covering the entire viewport? Any ideas/suggestions?
