[Mondrian] NON EMPTY + exception

[Julian Hyde]

Heed the error message "join does not have alias" - check all <Join>
elements in your schema and make sure that specify leftAlias and rightAlias,
to make the join unambiguous.

Subject: [Mondrian] NON EMPTY + exception


Hello all:

I am having a little problem with my cube. It has 3 dimensions.

The case is that, when I ask something like this:

select NON EMPTY Crossjoin(Hierarchize(Union({[Dim1].[All]},
[Dim1].[All].Children)), {[Dim2].[All]}) ON COLUMNS, 
  NON EMPTY {[Dim3].[All]} ON ROWS
from [MyCube]

and then, I expand Dim1 I get an exception like this:

SqlMemberSource.getMemberChildren: executing sql [ SQL query ], exec 46 ms,
exec+fetch 46 ms, 7 rows
com.tonbeller.jpivot.olap.model.OlapException:
mondrian.olap.MondrianException: Mondrian Error:Internal error: Error while
executing query: MDX query which should work 

...
...
...
...

Caused by: mondrian.olap.MondrianException: Mondrian Error:Internal error:
join does not have alias
...
...
...

Do you have any idea about what could cause this problem? I know that I have
not sent the complete log but, I hope this could help to troubleshoot the
problem. 

I remind: It ONLY happends when I ask for non empty cells. It DOES WORK when
they are allowd.


Thank you a lot:

Agustín
