Class DefaultErrorHandler

java.lang.Object
  org.gwtbootstrap3.client.ui.form.error.DefaultErrorHandler

All Implemented Interfaces:

ErrorHandler

public class DefaultErrorHandler
extends Object
implements ErrorHandler

This is the default ErrorHandler implementation. The assumption is that every ValueBoxBase instance will have a HasValidationState parent. If there is a HelpBlock that is a child of the HasValidationState parent then error messages will be displayed in the HelpBlock. Example:

  
      User
