Open GoogleCodeExporter opened 9 years ago

The following NPE was thrown when I was adding a 2nd dimension to the OLAP 
query. The Dimension has 2 differen hierarchies:

java.lang.NullPointerException

I just found out some more details:
When expanding the OLAP connection in the left hand tree the users sees the 
(shared ?) 
dimensions underneath the cube but also separate from the cube. If you either 
Add one 
of the separate dimensions and then a measure (and also the other way around) 
to the 
OLAP query, you'll get this exception. There is no exception if you select the 
dimension that is underneath the cube.
