    required=

    enrokuta Newbie

      Is the required attribute of the param tag in pages,xml dependent on any validator?

      I have a page parameter called st of type String that is required:

      <page view-id="/members.xhtml" action="#{memberListingService.setMemberList}">
       <param name="st" value="#{memberListingService.status}" required="true"/>
      </page>
      


      Now when I access the members.xhtml page without passing any parameters in the URL, I get a ValidatorException

      I don't know how the two are related but it seems that validation is performed even though the value of st is missing.

      On another note: messages_en.properties that SeamResourceBundle uses is missing the javax.faces.component.UIInput.REQUIRED_detail key. If you specify the "required" attribute of the param tag without this key you end up with the following exception
