BIRT Report Designer Issue
===

Okay, I am have a terrible problem with BIRT Report Designer (3.7.0, 3.7.2).  Here it is.  Using oracle.jdbc.driver.OracleDriver (v10.2), I applied a procedure as a dataset source for my report, you know {owner.procedurename(?,?,?,?)} in the query.  The first three are input parameters, and the last is an output parameter for cursor reference that I want to access from my procedure.  I'm getting a BIRT error message like invalid arguments in call.  All of the parameters are appropriately set up in BIRT.  

My boss shared an example with me that only works, if the user doesn't go into examine the dataset properties; otherwise, it just craps out.

My question is this: does BIRT support or not support using procedure output cursor parameters?  I have looked around on the internet, and there are some who say that this functionality is supported and others who say that it isn't.  I am fairly new to Eclipse/BIRT, and am  gathering that I could get this functionality to work if I used Eclipse with BIRT integrated, using the engine API, et cetera. Does that sound like a plausible approach?  I would be most grateful for any input.  Thanks very much for your time!  Matthew.
