featureLayer.queryFeatures appears to not execute the callback if there are no features that match the query.I have modified the following sample to illustrate (JS API 3.8):http://developers.arcgis.com/en/javascript/samples/fl_paging/If one replaces the contents of function queryRecordsByPage with the following (obviously without the line numbers): 1. var query = new Query(); 2. //query.objectIds = pageInfo.objectIds.slice(begin, end); 3. query.outFields = ["*"]; 4. query.geometry = featureLayer.fullExtent; 5. //query.geometry = new esri.geometry.Extent(-1, -1, 1, 1, 4326); 6. // Query for the records with the given object IDs and populate the grid 7. featureLayer.queryFeatures(query, function (featureSet) { 8. updateGrid(featureSet, pageNumber); 9. });
- updateGrid (line 😎 gets called with the code as it is shown above. This is expected, as our query geometry has points within it.- when I comment out line 4 and uncomment line 5, updateGrid (line 😎 doesn't get called at all (in this case, no points are within the custom extent).Is this normal behaviour for featureLayer.queryFeatures? I was hoping the callback would trigger, returning an empty feature set (so my code can react to the "nothing within this extent" case).Any feedback is appreciated. Thanks.
