How to set unsolved variables to zero in femstatic?

Just a quick one:
I need to solve a coupled electrostatic/magnetostatic problem where my conductivity tensor depends on variables in the magnetostatic problem.
The problem is quite heavy on the memory so I'd like to do it sequentially:
Electrostatic potential -> store solution -> Magnetic vector potential -> Store solution -> Electrostatic potential again.
For the first go on the electrostatic potential, all unsolved magnetostatic variables should just be zero, and I've tried adding the properties 'init',0 and 'u',0 which should do exactly that (well at least according to the Comsol Script generator), to my femstatic-call ie:
xfem.sol=femstatic(xfem, ...
'init',0, ...
'u',0, ...
'solcomp',{'V'}, ...
'outcomp',{'V'}, ...
'blocksize','auto', ...
'linsolver','spooles');
but no luck. It still returns an error stating that the unsolved variables are... well unsolved.
How should this be done correctly?
