[OpenLayers-Users] proxy problem again

Hi list,
sorry for adding another proxy problem post, but after several hours I still
could not figure out how to resolve this.
The setup is:
- html and OL javascript are served from test.local, which is my test laptop
and the same machine the browser runs on
- base layer is served from radl-routing.mdeport.de
- wms overlay is served by mapserver from dream.lrrl.arch.tu-muenchen.de
Display of the map including zoom/pan runs like a charm.
Now I want to query a point via WFS:
- wfs comes, as wms, from dream.lrrl.arch.tu-muenchen.de
- proxy.cgi is set up on test.local
- hitting http://test.local/cgi/proxy.cgi forwards to the openlayers websit
- hitting http://test.local/cgi/proxy.cgi?url=http://dream.lrrl.arch....
with a valid wfs request gives back the data in text/plain format as requested
and identically to the direct request to the wfs server
Having the following code in my map.html however results in an error:
function singleclick (e) {
setHTML("<p>Loading... <br>please wait...</p>");
var url = azdkadde.getFullRequestString(
{ REQUEST: "GetFeatureInfo",
EXCEPTIONS: "application/vnd.ogc.se_xml",
BBOX: map.getExtent().toBBOX(),
X: e.xy.x,
Y: e.xy.y,
QUERY_LAYERS: azdkadde.params.LAYERS,
RADIUS: 2,
WIDTH: map.size.w,
HEIGHT: map.size.h
} );
setHTML('<p>'+url+'</p>');
OpenLayers.ProxyHost = '/cgi/proxy.cgi?url=';
OpenLayers.loadURL(url, '', this, setHTML,
alert('failure calling '+url));
Event.stop(e);
}
the url is correctly written by the function setHTML, but the loadURL raises the
error as firebug shows:
[Exception... "'Permission denied to get property XULElement.accessKey' when
calling method: [nsIDOMXULLabelElement::accessKey]" nsresult: "0x8057001e

I already read http://en.wikipedia.org/wiki/Same_origin_policy but found no
violations of these rules in my code.
I would be glad if any knowledgable person could shed light on this.
Below the sig you find the output of the firefox dependencies information, I
could see no anomality here.
Kind regards - Markus
