[cellml-discussion] import bug in the CCGS?

Wed, 20 Dec 2006 23:54:35 -0800 

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.
