Oops, the formatting of the code snippet went haywire. Hope this is better:

Subject: [OpenLayers-Users] Popup doesn't work on embedded map
Hi All,
I have developed an OpenLayers application which uses WMSGetFeatureInfo and
Popup.FramedCloud to display a popup when the user clicks on a feature.
Currently everything sits on the same server (WMS server, Apache, MapServer,
map files, web pages, etc.) and the popup works nicely when the user clicks on
a feature.
However, when I embed the map into a page from a different web site (i.e. the
web page URL and the WMSGetFeatureInfo URL are different) the popup doesn't
work any more. I've tried to track the problem using firebug and firebug gives
an error "xmldom is null" whenever I click on a feature to activate the popup.
It looks as if there is something wrong with the XMLHttpRequest. Has anybody
had this problem before?
This is how I've defined the popup:
[start of code snippet]infoQuery = new OpenLayers.Control.WMSGetFeatureInfo({
url: queryServerURL, //Variable containing the URL of the WMS layer being
queried maxFeatures: 1, title: 'Identify features by clicking',
queryVisible: true, layers: [queryLayer], //The WMS layer being queried
eventListeners: { getfeatureinfo: function(event){ if (map.getScale() <
400000) { if (event.text.length != 0) { map.addPopup(new
OpenLayers.Popup.FramedCloud( "querypopup",
map.getLonLatFromPixel(event.xy), null, event.text,
null, true )); }; }; }
}});map.addControl(infoQuery);infoQuery.activate();[end of code snippet]
Are there any obvious error in my code that could be causing the problem?
Regards,
Frank.
