I have copied one IP and updated the OM, SI ( container elements)
Now it returns an error while activating "Expression must return interface type"
I made it sure that there is no reference to the old objects. However, it still refers to the old interface type.
Any clue around why this error is popped up?
Ruled out references of OM, MM and MT and DT to the old set.
TRied to create a new IP and though I had not given any referencce to old one, it gives me same error.
