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.

		this.joinType = dataSet.getJoinType( );
		this.matcher = new JoinConditionMatcher( left.getOdiResult( ),
				right.getOdiResult( ),
				left.getScope( ),
				right.getScope( ),
				dataSet.getJoinConditions( ) );
