I cannot get this feature to work. See the attached sample files.

I have a product file, prod.tex, two components, chap1.tex, chap2.tex and 
an evironment file containing \setuphead[chapter][incrementnumber=prod].

I first compile the whole product, then I compile chap2, but the chapter 
number is 1.
