I hope I am not walking a dead road but here is what I understood:
1. You have a side-bar
2. This side bar displays its content depending on the current page type
3. You would like to encapsulate your side bar.
----
Easiest solution I can think of is to dispose your side bar into sub
components and configure your sidebar component within the page:
page.tml:
<t:sidebar show="search, weather, about"/>
(show-parameter specifies which sub-components to show)
sidebar.tml:
....
<t:if test="showSearch">
<t:sidebar.search/>
</t:if>
....
Your Sidebar class must provide a way to parse the show and
to support the property showSearch:
like:
boolean getShowSearch() {
return show.contains("search");
}
This would be a clean and simple approach you might find useful.
Cheers,
Martin (Kersten)

Betreff: T5: Passing a component to layout
Sidebars in our application will change from page to page. Normally, I'd just
pass them from the page to the layout as a block defined in the page. However,
some sidebars will have forms whose events I'd like to trap within the sidebar.
Blocks can't do that of course. So I want my sidebar to be a component that
can trap the event.
I can do this by putting this on my page:
<t:layout sidebar="mySidebar">
...
<t:if test="false">
<t:pageSpecificSidebar />
</t:if>
...
</t:layout>
Then in the page class, I can do @InjectComponent private Sidebar
_pageSpecificSidebar; public Sidebar getMySidebar() {return _mySidebar; }.
Another possibility is to have the <div id="sidebar"> in the page template
rather than layout, but I'd rather keep the "sidebar" code in the layout.
I don't like having to use the <t:if> statement there to prevent the rendering
of the sidebar in the page. I'm sure there's a better way to do this.
Suggestions?
Bill
