Subject: Classes, methods: bug or what is wrong?

Hi,
I'm an Cfengine newbie, tried to use classes for achieving "per-host" or
"per-farm" promises, but something goes wrong.
>From the following code, isn't it supposed that bundle2 should not run if the
>agent executing the promise is not from "ONE" class?
Many thanks in advance!
/Eduard
Content for /tmp/1.cf
body common control
{
bundlesequence => { "one" };
}
bundle agent one
{
classes:
"ONE" or => { "someserver", "Saturday" };
methods:
"ONE" usebundle => bundle2 ("234");
}
bundle agent bundle2 (p1)
{
reports:
debian::
"$(p1)";
}
The results:
depsrv1 ~ # cf-agent -f /tmp/1.cf -I -K
R: 234
depsrv1 ~ #
And the verbose output:
depsrv1 ~ # cf-agent -f /tmp/1.cf -I -K -v
