multiple graph definitions work differently in bb-hosts and hobbitserver.cfg?

Hello,

I have hosts where I have several graph definition per rrd in bb-hosts, in the forms of TRENDS:*,test:test|test1|test2, with related test,test1,test2 definitions in hobbitgraph.cf

I would like to move those into the GRAPHS variable of hobbitserver.cfg but only the test entry is graphed if I put any of the following combination:

test:test|test1|test2
test:test1|test2
test:test1
test1

(I do a /etc/init.d/hobbit reload after each modification of the hobbitserver.cfg file)

Any hint?

Cheers,
Gildas
