I have run into a problem with the latest tiles-core snapshot:
tiles-core-2.0-SNAPSHOT-20060922.jar
and I do realize that it is a nightly build.
Specifically, some types of output from a tile do not seem to stay
within the tile itself. There seems to be a buffering issue. I have
tried to as briefly as possible to indicate the problem below where I
show the welcome page, tiles-defs.xml file, the layout page and an
affected tile page. I have temporarily placed a webapp at:
http://www.lansdaletutoring.com/tilesbug
that demonstrates the problem and can make the war file available if
desired.
The key file contents follow (or at least what I currently believe to be
key):
tiles-defs.xml:
<?xml version="1.0" encoding="ISO-8859-1" ?>
<!DOCTYPE tiles-definitions PUBLIC
"-//Apache Software Foundation//DTD Tiles Configuration 1.1//EN"

Notice that the title text ends up outside the html title tags and
apparently outside the tile itself. This problem is occurring in a
number of places in several different tiles in my webapp and makes it
pretty much impossible for me to create valid faces pages. I have
reviewed the open bugs and did not see this problem represented,
although I could of course have missed it. Have I misconfigured or
misused something or is this a new bug?
Just to be clear, I am not asking for configuration help from the
development group. At this moment I do believe that I have run into a
bug that isn't my own.
