I am getting a weird child table name when using a JoinDataSource with an ArcGISDynamicMapServiceLayer. The following web page shows my application which is taken from the ESRI samples and modified to try and get a rollup of a data table by precinct in NYC. The join is working fine but I cannot label it because it is generating a dynamic table name every time and I don't know how to get that value. Looking at the legend you will see Precinct_%xxx where xxx is a unique set of numbers that I can't find anywhere.
