openLayers and geoserver: WMSGetFeatureInfo does not return feature beyond wrapdateline

Question

I built a map made of several layers. I need to display the layers features fields at the place where the user clicks (see the controler code hereafter). The layers are correctly displayed and go across the dateline. If the user click on a feature, its fields values are written in a div. However, if I click on a feature beyond the dateline, my controler returns nothing. How can I force it (or force geoserver?) to consider clicks beyond the dateline?

var map = new OpenLayers.Map("map-id", options);

                    if (typeof(event.features[0])=='undefined'){document.getElementById('infoGeneral').innerHTML=' '; return};
                    for (ii=0; ii< event.features.length; ii++){
                        thisEEZNAME=event.features[ii].attributes['eez'];
