joemccall86 opened a new issue, #14586: URL: https://github.com/apache/grails-core/issues/14586
### Task List - [x] Steps to reproduce provided - [x] Stacktrace (if present) provided - [x] Example that reproduces the problem uploaded to Github - [x] Full description of the issue provided (see below) ### Steps to Reproduce 1. Create a parent domain object that aggregates two child domain objects, and one of those child domain object has the other child domain object as a property (https://github.com/joemccall86/cascade-delete-test/tree/master/grails-app/domain/cascade/delete/test) 2. Populate the domain objects and attempt to delete the parent domain object 3. Delete the object (force a flush to see the error immediately) ### Expected Behaviour The parent object is deleted, and deletions cascade onto the child objects ### Actual Behaviour The underlying database complains that a `null` value is being set for a non-nullable column. e.g.,: ``` org.h2.jdbc.JdbcSQLException: NULL not allowed for column "SELECTED_CHANNEL_ID"; SQL statement: update person set version=?, name=?, organization_id=?, selected_channel_id=? where id=? and version=? [23502-194] ``` Stacktrace: ``` 2018-02-20 16:10:06.995 ERROR --- [ Test worker] o.h.engine.jdbc.spi.SqlExceptionHelper : NULL not allowed for column "SELECTED_CHANNEL_ID"; SQL statement: update person set version=?, name=?, organization_id=?, selected_channel_id=? where id=? and version=?
