EmptyStackException in OLAP Analysis after Update to JasperServer 5.6

0

After updaten my JasperServer 4.5 to 5.6 I encountered a few issues with the OLAP analysis. I can open the analysis just fine, but if I try to expand a dimension in the CUBE settings I get the following exception:

java.util.EmptyStackException

I googled the error and found similar problems with Pentaho BI (they use the same OLAP engine an jpivot; they are also the creators of the Mondrian OLAP engine). It seems to be fixed in their system.

Has anybody encountered similar problems in Jasper BI and could provide a solution for this?

I also updated from 4.5 to 5.6 and I experience the exact same error.

Have you found a solution for this issue?

Best regards,

Michael

In the Mondrian JavaDoc (http://mondrian.pentaho.com/api/mondrian/olap/SchemaReader.html) I found the following:

If you use a SchemaReader from outside of a mondrian statement, you may get a EmptyStackException indicating that mondrian cannot deduce the current locus (statement context). If you get that error, call withLocus() to create a SchemaReader that automatically provides a locus whenever a call is made.


Could this be the reason for the error? How can I fix this? I couldn't find the source code for the custom Jaspersoft mondrian or jpivor implementations in the subversion repo.
