    [ http://opensource.atlassian.com/projects/hibernate/browse/HHH-5056?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=40069#action_40069 ] 

Ahmed Ali Elsayed Ali Soliman commented on HHH-5056:
----------------------------------------------------

First i use java property not a DB table.
Second: it doesn't work for hql either
when using (select id, name from bean) then using query.setResultTransformer(Criteria.DISTINCT_ROOT_ENTITY)
it returns one dimensional array with the last column [name] only not two dimensional array with [id, name]

> Criteria API with ProjectionList and Unique result

> 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.
