This activity can only be used in Microflows.
The cast object activity is used in a microflow after an object type decision to change the type of object from the generalized object type to the specialized object type of the path out of the object type decision.
To read more about specialization and generalization, see Entities.

4 Common Section
For more information on properties in this section, see Common Properties.
For example, there are three specializations of the Question object. Only an object of the specialized type MultipleChoiceQuestion needs to have some special actions performed on it. These will be done in a sub-microflow which has as the input type MultipleChoiceQuestion. Since an object of the type Question cannot get passed to the sub-microflow, the object first needs to be cast to the object type MultipleChoiceQuestion.
