4. Improved Trinidad Support
• Improved client-side validation
• Support for
• CoreOutputLabel
• LabeledFacesMessage
DI (FH) Gerhard Petracek / MyFaces-Extensions-Validator
20.04.09 4

5. 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

6. 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

7. 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)

8. 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);

9. 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)

syntax in view of cross-validation
