Bug 192332 Engine does not set values for parameters in a data extraction task
Engine does not set values for parameters in a data extraction task. So if a query binds a paramter, we can not get correct data from document.
engine/org.eclipse.birt.report.engine/src/org/eclipse/birt/report/engine/api/impl/DataExtractionTaskV1.java
.get( query );
				String queryName = item.getName( );
				if ( queryName == null )
				{
					queryName = "ELEMENT_" + item.getID( );
				}
				queryId2NameMapping.put( queryId, queryName );
				queryId2QueryMapping.put( queryId, query );;
			}
		}
		try
		{
			loadResultSetMetaData( );
		}
		catch ( EngineException e )
		{
			e.printStackTrace( );
		}
		isMetaDataPrepared = true;

	private String getQueryName( String queryId )

		return (String) queryId2NameMapping.get( queryId );
