Question about this: what is "custom_solver"? Is it something you've
added yourself? You can list the available solvers on your machine like
this:
zack@timira:~$ update-cudf-solvers -l
cudf: aspcud
edsp: dump
edsp: apt
edsp: aspcud
Unless you've added yourself a solver called "custom_solver" (see
README.cudf-solvers for info on how to do that), your command above
won't do anything meaningful.

As minor nitpicking: note that the above is not a *CUDF* scenario, it's
an EDSP one, which is an intermediate, Debian-specific format. (See the
EDSP protocol documentation shipped with APT for more info about it.)
That said, it is definitely not normal that the EDSP document contains
only the request, but:
1) I cannot reproduce the problem.
If you want to try in a solver-neutral version, you can for instance
try with this:
apt-get -s --solver dump install xfce4-panel/testing
and send us the resulting /tmp/dump.edsp file
2) it is indeed normal that in the request stanza there is no mention of
the fact you've asked to install from testing. That information is
"compiled" (by APT) to a numerical pin value + a boolean stating
which package is the installation "candidate". In my example above,
I correctly get an apt-pin value of 500 for the version of
xfce4-panel in testing, and an apt-candidate set to true for the same
package.

Because EDSP != CUDF
Cheers.
