[jboss-user] [JBoss Seam] - s:decorate vs ui:decorate - different behavior for multiple

[ASavitsky]

Are these two (Seam decorate tag and Facelets ui:decorate) supposed to be similar? For example, let's take the following template (taken from Seam docs) that decorates input fields with errors:

template.xhtml:
<ui:composition xmlns="http://www.w3.org/1999/xhtml"
  | 	xmlns:ui="http://java.sun.com/jsf/facelets"
  | 	xmlns:s="http://jboss.com/products/seam/taglib">
  | 	<s:span style="#{invalid ? 'color:red' : ''}">
  | 		<ui:insert name="label" />
  | 		<s:span rendered="#{required}"> *</s:span>
  | 	</s:span>
  | 	<s:span>
  | 		<s:validateAll>
  | 			<ui:insert />
  | 		</s:validateAll>
  | 	</s:span>
  | </ui:composition>

When we're using ui:decorate, there are two columns created in the table, one for label, another one for input field (but no error decoration, obviously):

<h:panelGrid columns="2">
  | 	<ui:decorate id="username" template="template.xhtml">
  | 		<ui:define name="label">Username:</ui:define>
  | 		<h:inputText value="#{user.username}" required="true" />
  | 	</ui:decorate>
  | </h:panelGrid>

When we're using s:decorate, it results in only one column being created, with both label and input field in it.

<h:panelGrid columns="2">
  | 	<s:decorate id="username" template="template.xhtml">
  | 		<ui:define name="label">Username:</ui:define>
  | 		<h:inputText value="#{user.username}" required="true" />
  | 	</s:decorate>
  | </h:panelGrid>

Is this a desired behavior? I wonder whether s:decorate is supposed to behave the same way in respect to its child components...
