ChoiceType::finishView()

Finishes the form view.

This method gets called for each type in the hierarchy starting from the top most type. Type extensions can further modify the view.

When this method is called, views of the form's children have already been built and finished and can be accessed. You should only implement such logic in this method that actually accesses child views. For everything else you are recommended to implement {@link buildView()} instead.
