Validation: @NotNull && required=true

[mvlach]

I have problem with this:

HibernateValidator is run when value is not empty - I have to use required="true" - OK

But, why I have to see the default UIInput validation message javax.faces.component.UIInput.REQUIRED, when I have my own @NotNull(message="messages['something.better']").

Is there any solution to disable the UIInput default validation message ?

Thanks Mila

I think thisis what you are after:

javax.faces.component.UIInput.CONVERSION Conversion error occurred
javax.faces.component.UIInput.REQUIRED required
javax.faces.component.UISelectOne.INVALID Value is not a a valid option
javax.faces.component.UISelectMany.INVALID Value is not a valid option
javax.faces.validator.NOT_IN_RANGE Specified attribute is not between the expected values of {0} and {1}
javax.faces.validator.DoubleRangeValidator.MAXIMUM Value is greater than allowable maximum of '{0}'
javax.faces.validator.DoubleRangeValidator.MINIMUM Value is less than allowable minimum of '{0}'
javax.faces.validator.DoubleRangeValidator.TYPE Value is not of the correct type
javax.faces.validator.LengthValidator.MAXIMUM Value is greater than allowable maximum of '{0}'
javax.faces.validator.LengthValidator.MINIMUM Value is less than allowable minimum of '{0}'
javax.faces.validator.LongRangeValidator.MAXIMUM Value is greater than allowable maximum of '{0}'
javax.faces.validator.LongRangeValidator.MINIMUM Value is less than allowable minimum of '{0}'
javax.faces.validator.LongRangeValidator.TYPE Value is not of the correct type

put into a file in my War Src area.

I refer to it in my faces.config

<!-- My Messages Please -->

This is on top of the messages you put into the messages.properies in the jar.

(there are a LOT more message that just this list!):

and you can in8l them of course.

If this is helpful then you might want to propose to add it to the FAQ...

Thanks for reply, but I don't know how to disable the displaying the UIInput default validation message. When the field isn't empty, the hibernate validation work good.
If the input is empty the UIInput default message is show - and I would like to don't show this but show the @NotNull.

Currently there is no way to utilize the message of @NotNull, you need to change the JSF validator message for required="true" globally.

[monkeyden]

There is no way to do it globally but you can use a phase listener:

import java.util.Iterator;

import javax.faces.application.FacesMessage;
import javax.faces.component.UIComponent;
import javax.faces.component.UIViewRoot;
import javax.faces.context.FacesContext;
import javax.faces.event.PhaseEvent;
import javax.faces.event.PhaseId;
import javax.faces.event.PhaseListener;

/**
 * Example messages.properties entries:
 * javax.faces.validator.LengthValidator.MAXIMUM="[fieldLabel]" value is greater than allowable maximum of {0} characters.
 * javax.faces.validator.LengthValidator.MINIMUM="[fieldLabel]" value must contain at least {0} characters.
*/

@SuppressWarnings("serial")
public class MessageListener implements PhaseListener {

 public PhaseId getPhaseId() {
 return PhaseId.RENDER_RESPONSE;
 }

 public void beforePhase(PhaseEvent e) {
 FacesContext fc = e.getFacesContext();
 UIViewRoot root = fc.getViewRoot();
 Iterator i = fc.getClientIdsWithMessages();
 while (i.hasNext()) {
 String clientId = (String) i.next();
 if(clientId != null) {
 UIComponent c = root.findComponent(clientId);
 if (c != null) {
 String fieldRef =
 (String) c.getAttributes().get("fieldLabel");
 if (fieldRef != null) {
 Iterator j = fc.getMessages(clientId);
 while (j.hasNext()) {
 FacesMessage fm = (FacesMessage) j.next();
 String s = fm.getSummary();
 s = s.replaceFirst("\\[fieldLabel\\]", fieldRef);
 fm.setSummary(s);
 }
 }
 }
 }
 }
 }

 public void afterPhase(PhaseEvent e) {
 }
}

Then specify the fielLabel in the f:attribute tag:

<h:inputText value="#{contactUs.email}" size="50" maxlength="75" required="true">
<f:attribute name="fieldLabel" value="Email"/>
</h:inputText>

Or, if you require completely different messages for each component, you could specify a resource bundle key

<h:inputText value="#{contactUs.email}" size="50" maxlength="75" required="true">
<f:attribute name="bundleKey" value="contactus.error.email.required"/>
</h:inputText>

Using the latter approach, you would get the resource bundle key from the component attributes map in the listener and replace the summary text altogether.

[monkeyden]

On second thought, this is of no use to you within the context of hibernate validation. This is strictly JSF. I'll be quiet now.

[konami]

As of JSF 1.2, the h:inputText control has requiredMessage attribute that you can customize for each input field's required error message.
