[NTG-context] Problem with external cross-references

[Jean-Philippe Rey]

Hello everybody,

I'm trying to use external cross-references between two files but I can't make it work with MkIV. I am using ConTeXt current

ConTeXt  ver: 2011.05.18 18:04 MKIV  fmt: 2011.7.31  int: english/english


With MkII, the following minimal example works perfectly well :

% file test_crossref1
\starttext
\chapter[lorem]{Lorem}
Lorem ipsum dolor sit amet, consectetur adipiscing elit \in{Chapter}[lorem].
\stoptext

% file test_crossref2
\usereferences[test_crossref1]
\starttext
Lorem ipsum dolor sit amet, consectetur adipiscing elit \in{Chapter}[lorem].
\stoptext


However with MkIV, I get an unknown reference (??) in test_crossref2 and the following lines in test_crossref2.log

[...]
system          > references from other files are handled automatically
[...]
references      > unknown reference [][lorem]
[...]

With 

% file test_crossref2
\starttext
Lorem ipsum dolor sit amet, consectetur adipiscing elit \in{Chapter}[test_crossref1::lorem].
\stoptext

I still get an unknown reference (??) and the following diagnosis in the log file
[...]
references      > references from document 'test_crossref1' are not exported
references      > unknown reference [][test_crossref1::lorem]
[...]

However when I add the export option in the test_crossref1 file

% file test_crossref1
\setupreferencing[export=yes]
\starttext
\chapter[lorem]{Lorem}
Lorem ipsum dolor sit amet, consectetur adipiscing elit \in{Chapter}[lorem].
\stoptext

I get an error at compile time. Below is the full log file. Does anyone know what I am doing wrong ?

Thank you for your help.
