Direct Known Subclasses:

AbstractPanelFormController

public abstract class AbstractBaseFormController
extends org.springframework.web.servlet.mvc.SimpleFormController
implements org.springframework.beans.factory.InitializingBean, FormController

Base form controller class for all controllers. Provides delegation to a method in the controller based on the value of the "method" field / parameter in the request.

Overrides the referenceData() method and delegates to setupReadModeReferenceData() if the request is considered to be in read mode or setupEditModeReferenceData() if the request is in edit mode.

Also provides helper methods for getting localised messages and saving messages to the session. Messages saved to the session should be used in conjunction with an appropriate cleanup strategy such as the UserResolvingInterceptor.
