Well, I was afraid it was too simple.  Seems that the lattice modifier 
code also depends on the fu,fv,fw,du,dv,dw parameters in the lattice 
structure, which aren't being updated via the current API.  They should 
be recalculated when resizelattice() is called (which happens in 
lattice.setPartitions()), but only if an object is also passed to the 
function.  I put in another hack which works for my current project, but 
haven't tried to delve into if there's somewhere else which also is 
setting these parameters.
