Build ID: 3.3.0   I20070625-1500

Steps To Reproduce:
1. Write an event handler that implements IScriptedDataSetEventHandler
2. Create a report design using your scripted data set and set some properties like "comments" and "customXml".
3. Put a breakpoint in the describe method and run the report in the debugger.
4. When the breakpoint is hit, note that by expanding the attributes of the IDataSetInstance you can see the "propValues" map and that the properties and their values are in that map.
5. Note that you cannot get to the property map from the IDataSetInstance because there are no accessible methods to do so.


More information:
It should be possible to request the value of a data set property from the IDataSetInstance argument directly, with a getPropertyValue method, for example.

The following reflection-based code that specifically forces inaccessible attributes to be accessible, does get to the property map, proving that the data is indeed there:

   Map<String,Object> myPropertyMap = getPropertyMap (aIDataSetInstance);
   . . .
