Examples of BindStatus

org.springframework.web.servlet.support.BindStatus
Simple adapter to expose the bind status of a field or object. Set as a variable both by the JSP bind tag and Velocity/FreeMarker macros.
Obviously, object status representations (i.e. errors at the object level rather than the field level) do not have an expression and a value but only error codes and messages. For simplicity's sake and to be able to use the same tags and macros, the same status class is used for both scenarios. @author Rod Johnson @author Juergen Hoeller @author Darren Davison @see RequestContext#getBindStatus @see org.springframework.web.servlet.tags.BindTag @see org.springframework.web.servlet.view.AbstractTemplateView#setExposeSpringMacroHelpers
