My guess is that your problem stems from the fact that you use primary
key fields for your foreign key fields which often leads to problems.
In general you should not do that - if you change the reference to
another object, then the identity of your object will change as well
which is most certainly not what you want.
Rather use seperate non-PK fields for the references. Or if the Report
and Scientist classes link back to the IOS class (bi-directional
link), then use collections instead in the IOS class.
