Re: Tiles 2 - problem with putList tag.

["David H. DeWolf" <dd...@apache.org>]

It may not have been announced to the user community yet (we're still 
getting things like our infrastructure and website up to snuff), but 
Tiles has graduated to a Top Level Project.  Because of this, we now 
have our own mailing lists.

I'm moving this discussion to users@tiles.apache.org, please continue it 
there.
