As far as I understood you are trying to validate data of object, using
user interface?

Wouldn't it be nicer to use proper Constraint for this type, and invoke
checkConsistency while validating object?

Using mass workflow transition with some asynchronous messaging would
give possibility to:
 a mass data insertion
 b then mass data validation
 c mass data edition, goto b until wrong objects left

And there might be some kind of tooltip on object, which would show
checkConsistency messages on object, while edited by user (eg. list
presence of duplications etc).

That's a way, we are implementing such constraining in our
implementation.

Regards,
Luke
