Subject [Myfaces Wiki] Update of "Extensions/Validator/ConceptOverview" by GerhardPetracek
Date Wed, 08 Apr 2009 09:45:41 GMT
Dear Wiki user,

You have subscribed to a wiki page or wiki category on "Myfaces Wiki" for change notification.

The following page has been changed by GerhardPetracek:

   * Processed information recorder
   * Renderer interceptor
   * Validation exception interceptor
+  * Metadata extraction interceptor (since 1.x.2)
  Most of the time you will just use the annotations of ExtVal. So you don't need these mechanisms.[[BR]]
  '''Just use the annotations and the rest is done by ExtVal.'''[[BR]]
@@ -90, +91 @@

  Allows to intercept validator exceptions thrown by ExtVal validation strategies.[[BR]]
  Example use-case: replacing the label-placeholder within the validation message with the
value of the label (e.g. see HtmlCoreComponentsValidationExceptionInterceptor)
+ === Metadata extraction interceptor (since 1.x.2) ===
+ Mechanism which allows to add/change/remove meta-data entries for the target property after
the meta-data extraction and before validation is processed.
