MGE and Firefox 3

[Le Ingenieur Inconnu]

Hello!
I cannot get MGE running with MGE (the map does not appear, even though the layer structure does). This happens only with projects based on web layouts. Projects based on fusion work fine.

Do you have any ideas on how to put it to work again?

At this point FireFox 3 is not a supported browser. Maybe someone can use Firebug to determine what the error(s) are which might help in providing a workaround.

Regards,

The problem seems to be with XMLHttpRequests returning empty content, which may be due to unsupported mimetype (ff3 accept header is text/html, while ff2 uses text/xml and the content type of the returned data is text/xml). Tryied to change the accept mimetype but no luck yet.

Hi!
The problem seems to be in the ajaxmappane.templ. RequestMap() uses a POST in the XMLHttpRequest but it seems that the MapAgent does not like some of the headers and the reply is empty. A quick fix for this has been to change it to a GET, appending the parameter list.

function RequestMap(scale, centerX, centerY, showGroups, hideGroups, showLayers, hideLayers)
{
// ...
mr = CreateRequestHandler();
req = new MapRequest(mr, ++mapId);
// -- FF3 Fix
mr.open("GET", webAgent + "?" + reqParams, true);
// -- Old code
//mr.open("POST", webAgent, true);
mr.setRequestHeader("Content-Type", "application/x-www-form-urlencoded");
// ...
}

Have you seen this?

(that's ticket #378 in the trac.osgeo.org/mapguide Trac instance if the
hyperlink doesn't work)

Hi!
I've seen the ticket but it seems to be open yet and scheduled for R2.1. For the time being I've been able to keep it working by replacing the posts with gets (three other functions need to be replaced, I've uploaded the file in the mapguide.osgeo user forum

Any change you could post a link to the file you uploaded?

Thanks

Scratch that. I think I found it:
