Bug 314631 Cann't get correct default values for parameters that with non-constant default value expressions
Steps to reproduce: 1. create a report with a scalar parameter that has non-constant default value expression such as BirtDateTime.today() 2. setup a project to get the default values of the parameter in BIRT runtime Eg. IReportEngine engine = createReportEngine( ); IRunnable runnable = engine.openReportDesign( REPORT_DESIGN ); IGetParamaterDefinitionTask task = engine.createGetParameterDefinitionTask( runnable ); HashMap result = task.getDefaultValues(); Expect result: The result map contains a parameter name and default value pair in which the default value is a Date instance of today. Actural result: The default value is null.

choices.add( new SelectionChoice( null, value ) );

				else
				{
					
					Object value = convertToType( result, dataType );
					choices.add( new SelectionChoice( null, value ) );
					return choices;
				}
				if ( !fixedOrder )
					Collections.sort( choices, new SelectionChoiceComparator(
							sortByLabel, parameter.getPattern( ),
							sortDirectionValue, ulocale ) );
				return choices;
			}
			catch ( BirtException e )
			{
				log.log( Level.FINE, e.getLocalizedMessage( ), e );
				executionContext.addException( e );
			}
		}
		return null;
