[Mondrian] RolapNativeSet NPE

[Matt Campbell]

Hi Hilario-
I was able to reproduce what you were seeing by setting ExpandNonNative=true.  Can you confirm you have that property set as well?  (I believe that's the default setting in biserver)

I've logged MONDRIAN-1964 for the issue.

Thank you for your reply.

I've tryed version 3.6.2 and 3.6.5 with the same results.

Should i fill in a bug report? Under which project should i do it? I've opened bugs in the wrong place in the past, just want to make sure i put it on the right place this time!

Looks like a bug.

Which version is this? I vaguely remember seeing this before.

Hi everyone,

I'm implementing a system that creates mdx queries and passes these to Mondrian to be executed. During my tests I have found a problem when using mondrian.native.crossjoin.enable=true.

If I try to do a query such as this:

SELECT
NON EMPTY {[Measures].[Price_SUM]} ON COLUMNS,
NON EMPTY CrossJoin({Filter({[Brand].[Brand].Members}, [Brand].CurrentMember.Name MATCHES '(?i).*zzzzz.*')}, {[Fuel].[Fuel].Members}) ON ROWS
FROM [Cars]


Where we have a CrossJoin of a Filter over Brand members with the fuel members. The problem is that whenever the first argument of the CrossJoin is a filter that returns empty (no values matched) i get a NullPointerException from mondrian.


java.lang.NullPointerException

Anyone has an idea of the problem?
