We've been running drools-guvnor on JBoss EAP 5 for quite some time now. Today I downloaded and installed JBoss EAP 6.1 and drools-guvnor 5.5. I got both started without any real problems; so far so good. My next step was to see if I could migrate everything from the guvnor 5.0 repository to the 5.5 repository. I used the admin export tool, saved the export, imported into guvnor 5.5 -- all cleanly: no errors of any kind. The screen refreshed... and less than half of my packages are present! On a whim, I tried to create a new package, one with the same name as one of my missing packages. Knowing package names need to be unique, I wondered if this might jog its memory. It failed to let me create the package, logging an exception: RulesRepositoryException: A module name must be unique So it would appear that my package exists somewhere in the repository, but I can't see it. In fact, I can search for functions and rules that exist in that package, open them, and save changes. But the package still doesn't appear. Anyone have any ideas on what went wrong or how to fix it? -- View this message in context: http://drools.46999.n3.nabble.com/Upgrading-Migrating-from-Guvnor-5-0-0-t...
