nlme error on dimensions in multiplication

---
The exp function in the example is used to constrain estimates of the
coefficients to positive values, when actually estimating log of the
coefficients with nlme.
When I try to debug, there find a mismatch between the dims of weights
and the dims of Matrix conLin$Xy generated by function MEdecomp, which
reduced the original 34 rows to just 6 rows.
I tried to remove double entries in my example, but this did not help.
How can I make proper use of nlme?
Yours,
