11 years ago Hi Gmonkey,
Thanks for your post. I upgraded this plugin to 2.2.1. While testing it with "grails test-app" I get below exception same like yours. Could you please let me know what you did to resolve it.
Cannot invoke method get() on null object. Stacktrace follows: Message: Cannot invoke method get() on null object Line | Method ->> 60 | beforeInsert in org.drools.gorm.session.SessionInfoDomain
| 46 | onApplicationEvent in org.grails.datastore.mapping.engine.event.AbstractPersistenceEventListener
| 86 | saveDomain . . . . . . . . in org.drools.gorm.GormDomainService
| 122 |
Thanks in advance. Himanshu
I have tried to run drools-gorm example and plugin validation tests and get the same error on 2.1.0 of grails. Note that I had to exclude hibernate-annotations to get the app to run. Any idea why this would be happening? The tests all successfully pass in 1.3.9 not sure why this is failing.
