Class DefaultErrorHandler

Object

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:

 <b:FormGroup> 
      <b:FormLabel for="username">User</b:FormLabel> 
      <b:TextBox b:id="username" ui:field="username" /> 
      <b:HelpBlock iconType="EXCLAMATION" /> 
 </b:FormGroup>
