This activity can only be used in microflows, not in nanoflows.
The Cast Object activity can be used in a microflow after an inheritance split to change the type of object from the generalized object type to the specialized object type of the path out of the inheritance split.
To read more about specialization and generalization, see Entities.
For the properties that all the activities share (for example, a caption), see Microflow Element Common Properties. This page only describes the properties specific to the action.

In this example, there are three specializations of the Question object. Only an object of the specialized type MultipleChoiceQuestion performs some special actions, which 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 get casted to the object type MultipleChoiceQuestion.
