Did you follow what the exception suggested-- invoke finalizeFromPrroperties() before writing the model to file?

You have to connect the force to something and this error suggests that the connections were not properly satisfied when you were constructing the model.

It may be useful to read through the API guide

hello...no i didnt invoke finalizefromproperties...i will invoke that...but what the exception suggested relate to finalizeconnection()...i want to know both finalizefromproperties() and finalizeconnection() must invoke before model.print() ?
