Hi all,

I'm running OpenNMS 1.6.2 on Windows server and am getting exceptions when 
making certain changes to KSC reports. Yesterday I created 6 or so KSC reports 
with no problem, but today whenever I try to change the configuration of the 
report I get the Exception error below. Sometimes it will let me add or change 
one or two graphs then goes back to generating these exceptions.

It happens after changing the properties of a particular graph, and clicking 
the "Done with edits to the graph" button.

Is this a known problem and is a fix available or planned? I couldn't find much 
with a search on "Could not find prefabricated graph report with name 'null'" 
in the archives or the website.

What further information can I provide to help in solving this problem?


org.springframework.orm.ObjectRetrievalFailureException: Could not find 
prefabricated graph report with name 'null'
