Cross-validation vs. Model- Aware Cross-validation • Cross-validation now detects the target automatically • That means: If the validation target isn’t available in the current request, validation is performed with the model value DI (FH) Gerhard Petracek / MyFaces-Extensions-Validator 20.04.09 5

Reverse Violation Messages • Model aware cross-validation might lead to • Inconsistent validation messages • Missing target to display validation error msg • Solution: reverse validation message • Optional possibility to provide a meaningful validation error message • Displayed at the source component DI (FH) Gerhard Petracek / MyFaces-Extensions-Validator 20.04.09 6

MetaDataExtractionInterceptors • Interceptor which is called after the metadata extraction and before the validation process • Possibility to add/change/remove constraints of the target property • Global mechanism • ExtValContext.getContext() .addMetaDataExtractionInterceptor(...) • @MetaDataExtractionInterceptor (available at the os890 ExtVal-Add-ons) DI (FH) Gerhard Petracek / MyFaces-Extensions-Validator 20.04.09 7

Optional Custom Skip-Validation Markers • Default marker for skipable validation strategies is: @SkipValidationSupport • Now it’s possible to provide • Custom marker annotation(s) • Directly the validation strategy which is skipable e.g. via: //optional: direct usage of validation strategies StaticInMemoryConfiguration config = new StaticInMemoryConfiguration(); config.addMapping(CommonMetaDataKeys.SKIP_VALIDATION, RequiredStrategy.class.getName()); ExtValContext.getContext() .addStaticConfiguration(StaticConfigurationNames .SKIP_VALIDATION_SUPPORT_CONFIG, config); DI (FH) Gerhard Petracek / MyFaces-Extensions-Validator 20.04.09 8

Pluggable Name-Mappers • Name-Mappers were located within factories • Now it’s possible to register name-mappers via ExtVal-Java-API – e.g.: ExtValContext.getContext().getFactoryFinder() .getFactory(FactoryNames.VALIDATION_STRATEGY_FACTORY, NameMapperAwareFactory.class)) .register(metaDataToValidationStrategyNameMapper) • Convenience methods are available at: ExtValUtils • @NameMapper (available at the os890 ExtVal-Add-ons) DI (FH) Gerhard Petracek / MyFaces-Extensions-Validator 20.04.09 9
