Newbie question on \completecontent

[Gerben Wierda <Sherlock@rna.nl>]

Suppose I create this document:

> \starttext
> \completecontent
> \chapter{One}
> \input tufte
> \chapter{Two}
> \input douglas
> \stoptext

I get a document with a content list and two chaqpters. Now I want to 
do the same in a project. I take the example from the manual and do 
this:

> %%
> %% This is the file book.tex
> %%
> \startproduct book
> \project teoade
>
> \startfrontmatter
>  \completecontent
> \stopfrontmatter
>
> \startbodymatter
>  \component chapters/chapter1
>  \component chapters/chapter2
> \stopbodymatter
>
> \startbackmatter
>  \completeindex
> \stopbackmatter
> \stopproduct

I get the chapters allright, but the list of contents and the index are 
empty. Why?

Thanks,

Gerben
