-------------------------------------

             Summary: NullPointerException in KieModuleMetaDataImpl.init
                 Key: DROOLS-854
                 URL: https://issues.jboss.org/browse/DROOLS-854
             Project: Drools
          Issue Type: Bug
            Reporter: Zuzka Krejčová
            Assignee: Mario Fusco


When creating certain types of assets in the gui, user gets an error modal: "Unable to complete your request. The following exception occurred: null."
The asset is created, but cannot be loaded (reopening results in the same error).
It seems that the newly created asset can be loaded after a project build.

Editors/assets affected are:
guided rules, guided rule templates, drl, guided score cards, guided dtables, guided decision trees, test scenarios
(others - enumerations, dsl, process definitions, ... are okay)

It might not be reproducible with drools-wb (based on irc conversations with [~wmedvede]).

Server log points to DMO:
