Dan Haywood commented on ISIS-164:
----------------------------------

This was originally raised as ISIS-18.  Some fixes were made under ISIS-18 that addressed a related problem, but didn't actually address this problem.  So have decided to clone ISIS-18 as this one, and update ISIS-18 to describe the issue that was addressed there.

> Currently the validate() method - used to check the overall state of an object, eg fromDate < toDate  - only applies for an object that has just been created but not yet persisted.
> If an object is pulled back from the object store and then updated, the object-level validation is not re-run.  For example that the fromDate could be modified > toDate; if there were no check in the modifyFromDate(), then the update would be allowed.
