Exposing an attribute using tiles

hello list,
I have the following code:

<tiles:insert definition="myLayout">
   <tiles:put name="body" type="string">
      <logic:iterate id="outageElement" name="searchForm" property="region1Papers">
         <tiles:insert page="/nextPage.jsp" flush="false"/>
      </logic:iterate>
   </tiles:put>
</tiles:insert>

and my nextPage.jsp contains this:
<bean:write name="outageElement" property="name"/>

When I run my code, I get the following error:
17:18:42,768 ERROR [Engine] ApplicationDispatcher[/oweb] Servlet.service() for servlet jsp threw exception
javax.servlet.jsp.JspException: ServletException in 'nextPage.jsp': No bean found under attribute key outageElement

Does anyone know how I could make nextPage.jsp aware of the 'outageElement'? I have been experimenting with <tiles:useAttribute> and <tiles:importAttribute>, but just can't seem to get it to work...

Any suggestions would be highly appreciated!

cheers,
pj

Beans are not passed automatically to a tile, but they can be passed as 
attributes.

Rewrite the first piece this way:

<tiles:insert definition="myLayout">
   <tiles:put name="body" type="string">
      <logic:iterate id="outageElement" name="searchForm" property="region1Papers">
         <tiles:insert page="/nextPage.jsp" flush="false">
           <tiles:put name="outageElement" beanName="outageElement" />
         </tiles:insert>
      </logic:iterate>
   </tiles:put>
</tiles:insert>


And your nextpage.jsp will be:

<tiles:insert attribute="outageElement" />
<tiles:importAttribute name="outageElement" />

<bean:write name="outageElement" property="name"/>

RE: Exposing an attribute using tiles

Posted by "Samere, Adam J" <as...@paychex.com>.
Tiles assembles pages using dynamic (runtime) inclusion. The logic:iterate tag defines a page scoped attribute under the key specified by the id tag attribute. The nextPage.jsp will have it's own pageContext, so the outageElement is not visible. Perhaps you could put the outageElement into request scope...
