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
IQueryDefinition query = getQuery( queryId );
					rsetId2queryIdMapping.put( rsetId, queryId );
					int count = -1;
					Integer countObj = (Integer) queryCounts.get( queryId );
					if ( countObj != null )
					{
						count = countObj.intValue( );
					}
					count++;
					String rsetName = getQueryName( queryId );
					if ( count > 0 )
					{
						rsetName = rsetName + "_" + count;
					}
					queryCounts.put( queryId, new Integer( count ) );
					rsetName2IdMapping.put( rsetName, rsetId );
					if ( null != query2ResultMetaData )
					{
						ResultMetaData metaData = (ResultMetaData) query2ResultMetaData
								.get( query );
						if ( metaData != null && metaData.getColumnCount( ) > 0 )
						{
							IResultSetItem resultItem = new ResultSetItem(
									rsetName, metaData );
							resultMetaList.add( resultItem );
						}
					}
