> when you make a select statement with Criteria API & use ProjectionList to retrieve some columns then use the unique result
> make at least 2 projection list (2 columns or more)
> ProjectionList projectionList = Projections.projectionList()			.add(Projections.property("ColumnA"))					.add(Projections.property("ColumnB"));
> criteria.setResultTransformer(CriteriaSpecification.DISTINCT_ROOT_ENTITY);
> the result must be retrieved in 2 dimensional array of Object(Object[][])
> but the result are one dimensional array with one column only.
> Note:- when you remove the unique result it works fine but when you add it, it make this behavior.
