* <p>Implementing this interface gives ActionBeans the chance to modify what
happens when the
- * binding phase generates errors. The handleValidationErrors method is
invoked after binding, but
- * before any custom validation is invoked (if the ActionBean implements
Validatable), and is
- * only invoked if there are errors. Also, note that setContext() will always
have been
- * invoked prior to handleValidationErrors(), allowing the bean access to the
event name
- * and other information.</p>
+ * binding and/or validation phase(s) generate errors. The
handleValidationErrors method is
+ * invoked after all validation has completed - i.e. after annotation based
validation and any
+ * [EMAIL PROTECTED] ValidationMethod}s that are applicable for the current
request. Invocation only happens
+ * when one or more validation errors exist. Also, note that [EMAIL PROTECTED]
setContext()} will always have
+ * been invoked prior to [EMAIL PROTECTED]
#handleValidationErrors(ValidationErrors)}, allowing the bean

do one or more

method is invoked, the

more of the following:</p>

* <ul>
* <li>Modify it's own internal state, e.g. unwind changes made by complex
setter methods</li>
* <li>Remove validation errors from the ValidationErrors object</li>
* <li>Add new validation errors to the ValidationErrors object</li>
* <li>Modify errors in the ValidationErrors object</li>
+ * <li>Any other operation, e.g. rollback a transaction, log an audit
message etc.</li>
* <li>(Optionally) Re-direct the flow of execution by returning a
substitute Resolution</li>

* <p>For example, if you want to override the validation service's results
and continue

this makes it

the errors. Doing this makes it

ActionBean you'd

came from, in that

change where the
