My process have a simple business object / variable. I have created a simple script that returns the new instance with the default values for the mandatory fields.
I have created an instantiation form with a simple text field, according to the contract defined for the instantiation step (object.attribute), but the value is never passed to the business variable. It's like the variables is instantiated AFTER the form as been invoked and submitted.
If I take a loot at the database, I see the default data returned in my script.
