I have a MapImageLayer on which I was using an IdentifyTask in version 4.0. Unfortunately that task is removed from version 4.1. I don't know why. It isn't mentioned in the documentation. Supposedly the QueryTask can be used instead. I need to get out the values from one single sublayer, so that would be a valid alternative for me. But I can't get the QueryTask to work on the MapImageLayer. Does anyone know if that can be done and if so, which parameters to use? I keep getting the message "Invalid or missing input parameter".
