[OpenLayers-Users] drillDown: multiple requests but only first in pop-up

[Giuseppe De Marco]

Using ol 2.12 with different layers configured in three different mapfiles on the same mapserver 6.x, Ubuntu 12.04.

<feature info>

new OpenLayers.Control.WMSGetFeatureInfo({
                            url: "http://"+ wms_hostname +"/cgi-bin/mapserv?map="+mapfile_path, 
                            title: 'Identify features by clicking',
                            drillDown: true,
                            infoFormat:'text/html',
                            click: 'true',

                            queryVisible: true,
                            eventListeners: {
                                getfeatureinfo: function(event) {
                                    map.addPopup(new OpenLayers.Popup.FramedCloud(
                                        "chicken", 
                                        map.getLonLatFromPixel(event.xy),
                                        null,
                                        event.text,
                                        null,
                                        true
                                    ));
                                    }
                                }
                            }), // fine getfeatureinfo

</feature info>

When I made a featureinfo query I can see 4 http request to my django proxy, using console debug.
Just the first request populates my FramedCloud, the second and the others: nothing to do, but they works ! 

If I copy n paste the request urls I can see, for the second request, the http-response with formatted html template.
The third and fourth aren't querable so I get the WMS message  that explain this.

How could  I wait for all the response and merge them into one single pop-up ?
