IdentifyTask return wrong/empty set of attributes

Discussion created by vaceslav.ustinov on Feb 2, 2014

We upgrade our ArcGis server from 10.1 to 10.2.

Now we get a wrong set of attributes when I execute IdentifyTask.

We have a Map-Service with 2 WorkspaceIDs defined. One is a Database connection and other one is FileGeoDatabase connection.
On the JavaScript side we define an ArcGISDynamicMapServiceLayer with JoinDataSource as DataSource.

The layer is displayed correctly. When I click on the layer the InfoWindow should show addition information. With ArcGis 10.1 it works properly, with 10.2 the Attribute-Set of json response is wrong (screenhot). We have other Map-Services and their IdentifyTask function work correctly. These Layers does not have JoinDataSource as Source.

Any suggestions?

Best Regards
