Class EscapedErrors

java.lang.Object
  org.springframework.web.bind.EscapedErrors

All Implemented Interfaces:

Errors

public class EscapedErrors

extends java.lang.Object

implements Errors

Errors wrapper that adds automatic HTML escaping to the wrapped instance, for convenient usage in HTML views. Can be retrieved easily via RequestContext's getErrors method.

Note that BindTag does not use this class to avoid unnecessary creation of ObjectError instances. It just escapes the messages and values that get copied into the respective BindStatus instance.

01.03.2003

Parameters:

nestedPath - nested path within this object, e.g. "address" (defaults to "", null is also acceptable). Can end with a dot: both "address" and "address." are valid.

getNestedPath

public java.lang.String getNestedPath()

Description copied from interface: Errors

Return the current nested path of this Errors object.

Returns a nested path with a dot, i.e. "address.", for easy building of concatenated paths. Default is an empty String.
