[OpenLayers-Users] Popup can not be closed when zooming

[Ivan Grcic]

voila:

var map = toolbarExample.app.vector.map;  // MAN you really hid your
map object well :P
var bygningLayer = map.getLayersByName('Bygning')[0];

bygningLayer.events.register('loadstart', this, function (evt){
if(selectedFeature && selectedFeature.popup){
        map.removePopup(selectedFeature.popup);
        selectedFeature.popup.destroy();
        selectedFeature.popup = null;
        selectedFeature = null;
        //selectControl.unselectAll();  // you are not closing your
popup on featureUnselect so this wont work for you...
        }
})

BTW you HAVE to use some of the loading strategies, i suggest bbox at least.

cheers
