Re: including one layout .jsp inside another?

[Bill Schneider]

I raised exactly the same question on this list a week or two ago.  I'm 
glad to see someone else attempting the same thing.

Two workarounds came out of that discussion--structure your tiles defs 
differently, or futz with tiles:importAttribute and tiles:put.  The 
first approach doesn't scale well, because for every page that includes 
tabs, you need two tiles defs instead of one.  (It gets worse if you 
have subtabs.)  The second approach works but is a kludge, not a clean 
solution.

Unfortunately, there does not seem to be a good way to handle this 
case with Tiles.

I am trying to define a layout, one component of which is another layout:
  definition name=main path=/WEB-INF/jsp/layouts/main.jsp 
put name=top value=/WEB-INF/jsp/common/top.jsp /
put name=leftNav value=/WEB-INF/jsp/common/leftNav.jsp /
  /definition

  definition name=tabs extends=main 
put name=body value=/WEB-INF/jsp/foo/tabs.jsp /
  /definition

  definition name=list extends=tabs 
put name=view value=/WEB-INF/jsp/foo/list.jsp / 
  /definition

  main.jsp:
  html:html
body
  tiles:insert attribute=top /
  tiles:insert attribute=leftNav /
  tiles:insert attribute=body /
/body
  /html:html
  tabs.jsp:
  tiles:insert attribute=view /
When I forward to list, main loads, it's children, including tabs,
but when tabs tries to load list as a child, I get this error:
  [ServletException in:/WEB-INF/jsp/foo/tabs.jsp] 
  Error - Tag Insert : No value found for attribute 'view'.' 

I have tried numerous variants of my tiles defs and tiles tags, but I
can't get it to work.

I dunno.. I've been doing this at least once every 2 or three weeks accidently with 
forwards and action classes.
I usually have an action class that forwards to a definition, and try to put it where 
I really want a jsp page.
Scales as well as your html is coded too
