[OpenLayers-Users] Doing something when the layer's features get deleted

[Adrian Popa]

I managed to find this (and fix my problem) for myself - by using 
beforefeatureremoved event:

markers.events.on({
         "featureselected": onMarkerSelect,
         "featureunselected": onMarkerUnselect,
         "visibilitychanged": onMarkerToggle,
         "beforefeatureremoved": onMarkerBeforeFeatureRemoved
     });

function onMarkerBeforeFeatureRemoved(evt){
     if(evt.feature.popup){
         //kill the popup
         map.removePopup(evt.feature.popup);
         evt.feature.popup.destroy();
         delete evt.feature.popup;
     }
}

Now, the popups no longer remain stuck if the layer refreshes...

Thanks!
