Bug 151535 Parameters are invisable in Joint Dataset
Trying to use "Joint Dataset" combined with parameters within underlaying Data-Sets (neccessary to achive a filtering where clause for a DateTime Field) Parameter editing ( e.g. in Chart designer) do not show the entire parameter. As specified it should show and let to edit a combination of both underlaying datasets' parameters.
data/org.eclipse.birt.data/src/org/eclipse/birt/data/engine/impl/PreparedJointDataSourceQuery.java
dataSet.getJoinConditions( ),
					false );
			IQueryResults right = getResultSetQuery( dataEngine,
					dataSet.getRightDataSetDesignName( ),
					appContext,
					dataSet.getJoinConditions( ),
					false );
			JointResultMetadata meta = getJointResultMetadata( left.getResultMetaData( ),
					right.getResultMetaData( ) );
			resultClass = meta.getResultClass( );
		}
		catch ( BirtException be )
		{
			throw DataException.wrap( be );
		}
