Chris, et al,
As of my last update to the nested tags, they use the request scope to store
their reference information. They used to browse the tree of tags on a page
which kept them in page scope, but now they're independent. If a nested tag is
run anywhere inbetween the start and end of a nested parent tag, it can get
the reference out of the request. This should allow all manner of include
methods, including Tiles.
The ability to do this is in the nightlies, you can wait for RC2, or download
just the nested tag update (and just throw it into your WEB-INF/lib) from...
http://keyboardmonkey.com/downloads/km-nested-v2.03.jar
...hopefully this is the answer you're looking for.
Arron.
