Vernon, The way I've always used Tiles is different from your approach. In the struts-tiles.xml definition file, my "template" could contain the components "title", "category", and "category_menu" with dummy values. The two tiles derived from "template", i.e. "landscape" and "water", would overload/override those fields as necessary. If you define an component named "styleSheet" in "landscape" but not in "template", when the page starts displaying the master tile (i.e. "template"'s /WEB-INF/jsp/template/main.jsp JSP), the master tile won't know about the "styleSheet" component you defined in the later child tile named "landscape."
My rule of thumb is that you define all components in the master tile(s). For any tile you extend, make sure you are only overriding previously defined components as you need them. They can initially be set to blank, i.e. "", in "template" so nothing shows up in the JSP unless you've overridden it in the "landscape" or "water" tiles. Why? Nesting and passing components can be difficult or awkward in Tiles if you are not VERY careful.'

The taglib statement is there as the following: <%@ taglib prefix="tiles" uri="http://jakarta.apache.org/struts/tags-tiles"; %> Absenting of the statement will lead to miss all insertions. In this case, only inserted text is missing. > > 2: To use "title" when you "extend" a master > template, I'm pretty sure you > MUST have a "title" component listed in your master > template too because you > are orverriding it in your "landscape" or "water" > templates. > I don't follow above. The inheritance is the following: water <- landscape <- template Nothing, including the "title", is overriden. > -----Original Message----- > From: Vernon [mailto:[EMAIL PROTECTED] > Sent: Wednesday, January 12, 2005 2:02 PM > To: user@struts.apache.org > Subject: [Tiles] Why the text does'nt show > > > In a project, I have the Tiles integrated with > Spring. > The inserted JSP files show up properly, but not > text. > I can't find the cause.
