problems nesting TileResults....

[Darren James]

Hello All,

I have a flow that is basically a toplevel struts2 action having a
result of type TilesResult.  That tile
result has as one if it's attributes another struts2 action that also
has a result of type TilesResult.
So my tiles.xml looks like this (I've changed names and attributes to
try to simplify the example
as much as possible)

    <definition name="pageLevelTile" extends="somePageLevelTemplate">
        <put-attribute name="header"  
value="/WEB-INF/tiles/pages/header.jsp" />
        <put-attribute name="body"     value="/findTileBody.action" />
    </definition>


    <definition name="moduleLevelTile" extends="someModuleTemplate">
        .... stuff
     </definition>

-----------

So i have an action, call it showPage.action that forwards to
pageLevelTile, then
within pageLevelTile the "body" attribute invokes the action
findTileBody.action
that eventually forwards to the moduleLevelTile.

The issue with this is the browser only renders the moduleLevelTile (all
the
surrounding page-level stuff gets wiped out for some reason), and I'm
seeing this
exception:

It's not a limitation, it's a bug :-)
https://issues.apache.org/struts/browse/TILES-232

Try using the SVN version of Tiles (branch: TILES_2_0_X):
http://svn.apache.org/repos/asf/tiles/framework/branches/TILES_2_0_X/
Or you can use the 2.0.6 snapshots:

Hi Antonio,

I got a 2.0.6 snapshot and the issue is fixed!  Thanks much for the
tip.  Also noteworthy is that
now that I have actions that can forward to tiles which have nested
within them actions that also
forward to tiles (whew), in order for action context to be available to
JSP pages I had to follow
the steps to include the struts-cleanup filter in web.xml.  The docs on
the struts2 site say that this
filter is solely for the purpose of sitemesh integration, but apparently
it's beneficial to tiles
integration as well....

thanks again,

- Darren.
