From the Seam Reference Guide:

32.1.3.1. <s:decorate>

Description

"Decorate" a JSF input field when validation fails or when required="true" is set.

Attributes

template: the facelets template to use to decorate the component

#{invalid} and #{required} are available inside s:decorate; #{required} evaluates to true if you have set the input component being decorated as required, and #{invalid} evaluates to true if a validation error occurs.

Usage

<s:decorate template="edit.xhtml">
 <ui:define name="label">Country:</ui:define>
 <h:inputText value="#{location.country}" required="true"/>
 </s:decorate>

<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':''}">
 <s:validateAll>
 <ui:insert/>
 </s:validateAll>
 </span>
 <s:message styleClass="error"/>

 </div>

</ui:composition>

#{invalid} and #{required} are available inside s:decorate; #{required} evaluates to true if you have set the input component being decorated as required, and #{invalid} evaluates to true if a validation error occurs.

Wow, thanks very much. That's exactly what was missing. I went back and checked Seam in Action, and indeed, the reRender attribute is there. I'm not sure how I managed to leave it off.

Guess I feel pretty stupid about now.

Thanks again.
