When trying to deploy a model (that I haven't started up in a long time and that I have converted from modeler version 2.4.2 to 18.104.22.168), the X-as shows the following error: INFO - COREACTIONMANAGEMENT: Exception occurred in action 'EventExtendedAction :: - action: [StartupAction] - before: [MxModelReflection.ASuCheckMetamodel] - replace: null - after:  ', all database changes executed by this action were rolled back ERROR - CORE: An exception occurred during XAS initialization Does anybody know what went wrong here?
The answer seems to be rather simple (after asking Jasper, so points to him). I've updated the Java actions but I didn't use the latest version of the model. This killed the Excel importer and caused the error.
Disable the startup flow @ "Project settings -> Events -> After startup".
You are most likely using an old version of Jasper's MxModelReflection module, so it would be best to ask him for advice.
