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.

					( (DynamicFilterParameterDefn) pBase ).setLocale( locale );

				{
					( (ParameterGroupDefn) pBase )
							.setDesign( designHandle );
					Iterator iter2 = ( (ParameterGroupDefn) pBase )
							.getContents( ).iterator( );
					while ( iter2.hasNext( ) )
					{
						IParameterDefnBase p = (IParameterDefnBase) iter2
								.next( );
						if ( p instanceof ScalarParameterDefn )
						{
							( (ScalarParameterDefn) p )
									.setDesign( designHandle );
							( (ScalarParameterDefn) p ).setLocale( locale );
							( (ScalarParameterDefn) p ).evaluateSelectionList( );
						}
					}
				}
