Hello Grails community I have an already existing Grails app that i have added the multi tenancy implementation so that each user in my app has it own family database schema. Family has a property of string familyName. The family name is used to created the database schema during insert. Parent belongs to a family Children has parent, so, it inherits from Parents. My issues is whenever i create a family, the database gets created alright but the data does not get persisted in the new created database, at the end i get an error Caused by: java.lang.NullPointerException: Cannot invoke "org.grails.orm.hibernate.cfg.Mapping.getBatchSize()" because "m" is null After reading around, I keep getting response that this is an inheritance issue from Hibernate affecting grails. Has anyone faced this issue or how could i resolve this For more insight on my set up, I have uploaded the app on github -> https://github.com/user-yormen/grails-multi-tenant-with-inherited-domain
