You can also use a controller class/action to do it
<tiles:insert definition="erp.mainLayout" flush="true"
controller="/selectBodyTile.do"/>
and then in the action class for /selectBodyTile.do you can access the
ComponentContext which will allow you to change the attributes before tiles
does the insert thus allowing you to programmatically set the inner tile to
be a JSP,another tile, etc. of your choice.
class SelectBodyControllerAction extends Action {
public ActionForward execute( ActionMapping mapping,
ActionForm form,
HttpServletRequest request,
HttpServletResponse response)
throws Exception {
ComponentContext temp =
ComponentContext.getContext(request);
if(isFullMoon(request)) {
temp.putAttribute("body", "fullmoon.jsp");
} else {
temp.putAttribute("body", "justanotherday.jsp");
}
return super.execute(mapping, form, request, response);
}
}
Controllers can also be a Derivative of TilesController which gives you the
Context as a param
