Don't use screen objects, use pull tool(s). Read the pull-tool docs on the
Turbine site. The only reason left for needing a screen object is security.
Name your screen template the same as the layout you want to use:
/layouts
Printable.vm
Default.vm
/screens
Printable.vm
Index.vm
Other.vm
When Index.vm and Other.vm are rendered, turbine will use Default.vm. When
the Printable.vm screen is rendered, it will use the Printable.vm layout.

Subject: Pull Tool Re: Cannot get correct Layout with my Reflect(ing) Screen
Dookie!
After reading the NumberFormatter Pull Tool thread,
maybe I should be making this a pull tool.
BUT, I'm still tired of having a bazillion Screen
classes that are the same thing over and over. How
can I have one Screen serve different screen templates
AND LAYOUT TEMPLATES and have it work correctly (not
use Layout DefaultLayout - during my investigation I
had set default.layout to DefaultLayout it TR.props;
this is the layout I'm seeing).

"I'm concerned about a better world. I'm concerned about justice; I'm
concerned about brotherhood; I'm concerned about truth. And when one is
concerned about that, he can never advocate violence. For through
violence you may murder a murderer, but you can't murder murder. Through
violence you may murder a liar, but you can't establish truth. Through
violence you may murder a hater, but you can't murder hate through
violence. Darkness cannot put out darkness; only light can do that."
