Hi Ranganath 
Thanks for reporting this issue.
So that I can look into it more easily, could you prepare a small example project (eg up on github) that demonstrates the problem for me?

> Scenario is:
> There is 1-N relationship between MOrganisation and OmOrgExtendedAttr entities. MOrganisation is parent entity and OmOrgExtendedAttr  is child entity.
> OmOrgExtendedAttr cannot exist without MOrganisation.
> MOrganisation can exist without OmOrgExtendedAttr 
> So on delete of MOrganisation, OmOrgExtendedAttr  is also deleted. There is no problem in this case.
> But problem is on delete of OmOrgExtendedAttr . The error that is coming is NullPointerException in FrameworkSynchronizer of isis-objectstore-jdo-datanucleous component for adpater for the POJO.
> Please find attached log and also the java files
> Could you please help on this issue ASAP.
> Thanks
