Hi All .. We are getting the following error message in Guvnor when trying to access it. org.drools.repository.RulesRepositoryException: javax.jcr.InvalidItemStateException: property /drools:repository/drools:package_area/com.lsi.sort/assets/Lotting Guidelines/drools:content: the property cannot be saved because it has been modified externally. This occurs in our production system and it is occurring rarely (So We couldn t reproduce it locally in our environment). But this issue is resolved when we restarted the Server in which the Guvnor app is running. But this is nearly impossible as this occurs in production system. We are using Oracle DB as our Persistent Manager (as seen in the attachment) and running the guvnor in clustered environment. I presume that the issue might be related to versioning in Guvnor ? If so can anyone guide us to solve this versioning problem ? Herewith attached the repository.xml file. Thanks in advance, Prasanna Venkataraman. repository.xml <http://drools.46999.n3.nabble.com/file/n4021115/repository.xml> -- View this message in context: http://drools.46999.n3.nabble.com/InvalidItemStateException-while-accessi...
