[tiles] programatically putting a definition into a layout

[William Salvucci <Wi...@dn.netl.doe.gov>]

with the following tiles-def, I can forward to layout.main and everything is fine:

definition name="layout.main" path="/layoutMain.jsp">
    <put name="header" value="header.jsp" />
    <put name="app" value="layout.app" />
    <put name="footer" value="footer.jsp" />
  </definition>

  <definition name="layout.app" path="/layoutApp.jsp">
    <put name="mainMenu" value="menu.main" />
    <put name="subMenu" value="subMenu.jsp" />
    <put name="body" value="welcome.jsp" />
  </definition>

  <!-- Menu bar definition -->
<definition name="menu.main" path="/menu.jsp" >
  <putList name="items" >
    <add value="Item 1" />
    <add value="Item 2" />
    <add value="Item 3" />
  </putList>
</definition>

I then modify the tiles-def so that in layout.main app = "logon.jsp" where logon.jsp submit is associated with a struts action. In the struts action I set the layout.main app = "layout.app" 

ComponentDefinition layout = TilesUtil.getDefinition("layout.main", request, this.servlet.getServletContext());
      layout.put("app", "layout.app");

and forward to "layout.main". So basically after the action everything should be the same as my original setup. However, I get the following error on the forward

<Jun 20, 2003 1:16:00 PM EDT> <Error> <HTTP> <Included resource or file "/netl-c
ommons/layout.app" not found from requested resource "/netl-commons/layoutMain.j
sp".>

layoutMain.jsp is not changed during my update and looks like

<TABLE border="1">
  <TR><TD COLSPAN="2"><tiles:insert attribute="header"/></TD></TR>
  <TR><TD COLSPAN="2"><tiles:insert attribute="app" /> </TD></TR>
  <TR><TD COLSPAN="2"><tiles:insert attribute="footer"/></TD></TR>
</TABLE>

Any idea why layoutMain.jsp could load layout.app in the original, but can't when I programatically put it into layout.main? I noticed that the put method doesn't have type as an argument for specifying "string", "page", "definition", so I hope that isn't it.

  It is not recommended to change a definition dynamically, unless you 
know very well what you do. A definition content is shared by all the 
website. Changing the content will be reflected to all user of the 
definition. If you want to change a definition attribute for the current 
tiles, you should do so in the tile context, which hold a temporary copy 
of the definition.

  The layout.app name has been interpreted as an URL.  It appear that 
the Tiles mechanism hasn't catch it.
  I don't see how you call the action from the logon.jsp page.
