Casting in bi-directional relationships?

[JohanDoornenbal]

I have a general object Assessment that I would like to apply to 'targets' of 
many different Types in the application.



In order to be as generic as possible I have set the class of the target of the 
Assessment to 'Object' (private Object target;)

        Now if I make a collection on an other object that takes Assessments 
using @Persistent(mappedBy = "target", dependentElement = "true") JDO cannot 
map to target.

        

        Anybody has a suggestion?
