I have attached two implementations of the same equation, y = sin(x).
In the case where the equation is given in a component within the same
model as its parent in the encapsulation hierarchy (import_bug-ok.xml)
everything works fine and CellML2C gives me the expected code.
If I move the exact same component to a separate model (sin.xml) and
import it (import_bug-fail.xml) then CellML2C tells me the model is now
overconstrained. But as far as I can tell it is the exact same model.
Can anyone spot an obvious mistake or is this a bug in the CCGS?
Thanks,
David.
