I'm using Tiles and I'd like an attribute defined for a page to be readable inside of one of the included subpages as follows:

tiles-definitions.xml:

<definition name="page" template="/WEB-INF/tiles/layout/page.jsp">
  <put-attribute name="header" value="/WEB-INF/jsp/_include/header.jsp"/>
  <put-attribute name="footer" value="/WEB-INF/jsp/_include/footer.jsp"/>
</definition>

<definition name="tutorial" extends="page">
  <put-attribute name="title" value="Tutorial"/>
  <put-attribute name="body" value="/WEB-INF/jsp/tutorial.jsp"/>
</definition>

The page.jsp represents a simple page structure:

<html>
  <head><title><tiles:getAsString name="title"/></title></head>
  <body>
      <tiles:insertAttribute name="header"/>
      <tiles:insertAttribute name="body"/>
      <tiles:insertAttribute name="footer"/>
  </body>
</html>

I'm trying to read the title also inside the "header" subpage but I get the following error:

org.apache.tiles.template.NoSuchAttributeException: Attribute 'title' not found.

Here is how I'm trying to access the attribute in header.jsp:

<tiles:getAsString name="title"/>
