I send off what look to be extremely similar filter requests to the same server. The first is fine, the second doesnt work - server reports error:

Code produces the first result is: wfsProtocol[i] = new OpenLayers.Protocol.WFS.v1_1_0({ url: lay.spatialQuery[0].url, geometryName: "SHAPE", featurePrefix: lay.spatialQuery[0].featurePrefix, featureType: lay.spatialQuery[0].featureType, srsName: (projstr=="EPSG:900913"&& (lay.serverUrl.search(/arcgis/)>=0)) ?
