Portlet MVC, Validation (JSR-303)

[flavouski]

Using Spring 3.0.2 and Hibernate Validator 4.0.2.GA

It looks like I have my validator setup correctly, but when I do:

//some of my imports
import javax.validation.Valid;
import org.springframework.validation.BindingResult;
import org.springframework.web.portlet.bind.annotation.RenderMapping;

@RenderMapping(params = "action=form")
public ModelAndView form(@ModelAttribute("formInfo") @Valid Form info, BindingResult binder){
		
		System.out.println("Errors Found:  "+binder.hasErrors());
		
		return new ModelAndView("formSuccess");
	}

My binder never has any errors. Yet when I do a:

validator.validate(info, binder);
System.out.println("Errors Found:  "+binder.hasErrors());

It has 3 errors, which is good. My "...-portlet.xml" looks like:

<?xml version="1.0" encoding="UTF-8"?>

	</bean>
	
	<bean id="validator"
      class="org.springframework.validation.beanvalidation.LocalValidatorFactoryBean"/>
	
	<!-- JSR-303 support will be detected on classpath and enabled automatically -->
    <mvc:annotation-driven/>

	
</beans>

In my libs folder I also have the

• validation-api-1.0.0.GA.jar
• hibernate-validator-4.0.2.GA.jar

Why won't my @Valid load any errors into my BindingResult?
Thanks

It looks like my @Valid and my Binder contain different validators due to the autowiredness, but I'm unsure how to correct this.

Looks like it will be fixed in 3.1 M1
