Hi. I am working with OpenLayers 2. I am using the events "loadstart" and "loadend" from here<http://dev.openlayers.org/docs/files/OpenLayers/Layer-js.html#OpenLayers.Layer.events> .
When I use OpenLayers.Layers.WMS, i want to have some kind of callback when there is a loading error. For example, when I enter an incorrect SLD filter, I want to have some feedback about the layer not being loaded correctly. Unfortunately, "loadend" doesn't provide this kind of error detection. I already found this question<http://lists.osgeo.org/pipermail//openlayers-users/2012-January/023772.html> where someone else has the same problem. In my searches, I have found this patch<http://trac.osgeo.org/openlayers/ticket/3265>for "loadfail", which I tried to apply on an uncompressed version of OpenLayers. Unfortunately, it didn't work. I have load errors that aren't detected and I need to know if there are load fails/errors. Could you put this event in a new fix of OpenLayers, please? If it is already there, how could I use it? Thank you. João
