Mendix 6.9 rollback issue

Hi, We have Enity A and Entity B with 1-1 association. We are creating the two objects, the association and committing them before opening a page. User can opn a modal on this page and edit the entities. When user clicks on cancel button on the modal, we are rolling back entity A and entity B but this is setting the association between them to empty in cache. This used to work in Mendix 6.6 Please advise.

This seems a bug to me. It should revert to the last commit so if the association was set prior to the commit it should have kept that association. If you could reproduce this in a small test project I would file a support request and attach that test project to it.
