Platform:
Browser: FF 3.6.13 on Fedora Core 14 x86_64
Client: Openlayers 1.4.10
Server: Geoserver 2.0.2
I am displaying a WFS vector highlight on top of a WMS raster layer.
Both are coming from the same postgis layer. The code used to show the
highlight is:
function highlightID(hid) {
var hf=new OpenLayers.Filter.Comparison({
type: OpenLayers.Filter.Comparison.EQUAL_TO,
property: "id",
value: hid
});
highlight.filter=hf;
highlight.setVisibility(true);
highlight.refresh({force: true});
}
When an element is highlighted I get the following error in Firefox:
uncaught exception: [Exception... "Component returned failure code:
0xc1f30001 (NS_ERROR_NOT_INITIALIZED) [nsIXMLHttpRequest.send]"
nsresult: "0xc1f30001 (NS_ERROR_NOT_INITIALIZED)" location: "JS frame ::
http://localhost/{app}/openlayers/lib/OpenLayers/Request/XMLHttpRequest.js
:: anonymous :: line 200" data: no]
However, the application works as expected. The code line in
lib/OpenLayers/Request/XMLHttpRequest.js
is:
200 this._object.send(vData);
Changing this line to:
try { this._object.send(vData); } catch (e) {}
Removes the error and the application still works as expected. I am
pretty sure this is not a cross-domain policy issue as I am piping the
application and geoserver through the same http host and port using
apache ProxyPass. The http base address that threw this error was
http://localhost/
