I had an issue earlier this week when trying to compute a gradient

because the differentation variable was not present in the form

the Constant with a Function over R resolved the issue immediately.
I think that's just a missing try/except catch in the relevant spot.
Can you supply the example?
On a side note: we might want to reconsider the naming
of the ScalarParameter and InitialConditionParameter:
As far as I've understood now, the latter refers can be any Function
(not just the initial condition for the state variable) however,
this was absolutely not transparent to me.
Yep, it just means the initial value of *any* Function, not just
the state variable. I agree that is unnecessarily confusing.
How about
ScalarParameter -> ConstantParameter
ScalarParameters -> ConstantParameter (fold the two)
InitialConditionParameter -> InitialValueParameter ?
(suggestions welcome)
SteadyFunctionParameter?
NonsteadyFunctionParameter?
SteadyDirichletParameter?
NonsteadyDirichletParameter?
(these last two will require some cooperation from Dolfin)
