problems with seam 2.0.0GA and custom validation messages

[kosl]

Hi all,

I'm trying to do a simple thing. I'm having a backing bean with such methods:

 @NotNull(message="test")
 public String getLogin()
 {
 return login;
 }

 public void setLogin(String newLogin)
 {
 login = newLogin;
 }

I'm also having a form (based on documentation):

<ui:composition xmlns="http://www.w3.org/1999/xhtml"
 xmlns:ui="http://java.sun.com/jsf/facelets"
 xmlns:h="http://java.sun.com/jsf/html"
 xmlns:f="http://java.sun.com/jsf/core"
 xmlns:s="http://jboss.com/products/seam/taglib">

 <div>

 <s:label styleClass="#{invalid?'error':''}">
 <ui:insert name="label"/>
 <s:span styleClass="required" rendered="#{required}">*</s:span>
 </s:label>

 <span class="#{invalid?'error':''}">
 <h:graphicImage src="img/error.gif" rendered="#{invalid}"/>
 <s:validateAll>
 <ui:insert/>
 </s:validateAll>
 </span>

 <s:message styleClass="error"/>

 </div>

</ui:composition>

 <s:decorate id="loginDecoration" template="/templates/forms/validateField.xhtml">
 <ui:define name="label"><h:outputText value="#{messages.login}"/></ui:define>
 <h:inputText id="login" value="#{register.login}" required="true">
 <a4j:support ajaxSingle="true" event="onblur" reRender="loginDecoration" bypassUpdates="true"/>
 </h:inputText>
 </s:decorate>

Unfortunatelly the custom message ain't displayed. Any1 has any suggestions what may be the cause?

Thanks in advance,

Karol

When I use the same code with @Lenght validation all is working fine. Am I right that it's caused by the problem described in documentation:

Note: specifying @NotNull on the model does not eliminate the requirement for required="true" to appear on the control! This is due to a limitation of the JSF validation architecture.

?

If so is there any way to customize validation error message for required=true constraing?

This is a very common JSF problem. required=true must be specified because JSF will not kick off any validation for empty fields. This means that you are limited to the REQUIRED message unless you do your own custom handling. The approach I've used in the past can be found at:

http://www.oracle.com/webapps/online-help/jdeveloper/10.1.3/state/content/navId.4/navSetId._/vtTopicFile.jsf_apps%7Ceventvalidate%7Csf_amg_messagesoverride~html/

Under "Add Field Reference Information to a Message." I've also seen slightly different takes on this approach in a number of blogs. Hope that helps.
