Yes, it does.

Now an OT bug. :-)

I added the "import PyTrilinos" to demo_poisson.py and got a ufl.Form error.

$ python demo_poisson.py

Deprecated: ufl.Form has no properties '*_domains'.
To associate domains with a form, use dss = ds[mydomains]; a = f*dss(1).
Traceback (most recent call last):
  File "demo_poisson.py", line 63, in <module>
    problem = VariationalProblem(a, L, bc)
  File

    self.a = Form(a, form_compiler_parameters=form_compiler_parameters)

    if form.cell_domains is not None:

ufl.log.UFLException: Deprecated: ufl.Form has no properties '*_domains'.
To associate domains with a form, use dss = ds[mydomains]; a = f*dss(1).

I guess this will be fixed with the pending 1.0 release.
