Hello,
I am using the Pentaho Aggregate Designer (Enterprise Edition 3.6)  and 
generated 3 Aggregate tables. But am unable to populate these aggregate tables 
with data. 


The Log reports the following message:

ERROR [org.pentaho.ui.xul.impl.AbstractXulDomContainer] Error invoking method: 
exportHandler.saveDml() java.lang.reflect.InvocationTargetException

ERROR [org.pentaho.ui.xul.swing.tags.SwingButton] Error calling oncommand event:

Caused by: java.lang.NullPointerException

Any Suggestions would be helpful.

Thank You.
