Double aggregate problem

Dear anyone,

I have the following query:

select v.id, array_to_string(array_accum(s.name),', ') as sector ,
array_to_string(array_accum(p.name),', ') as provincie from tblvacature
v, tblaccount a , tblvacaturesector vs, tblsector s ,
tblvacatureprovincie vp, tblprovincie p where v.id = 11 and v.account =
a.id and vs.vacature = v.id and s.id = vs.sector and vp.vacature = v.id
and p.id = vp.provincie group by v.id, v.inserted order by v.inserted
desc

That currently produces the following output:

id |                      sector                       |
                  provincie
----+---------------------------------------------------+---------------
-------------------------------------------------------------------11 | Gaafjes, Eerder, Gaafjes, Eerder, Gaafjes,
Eerder| Noord-Holland,  

Noord-Holland, Limburg, Limburg, Oost-Vlaanderen, Oost-Vlaanderen

If i leave out one aggregate, the result is as i expect (if I leave out
'provincie', sector gives):

Gaafjes, Eeerder

Only two results.

I would like both array_accum returning only what they should and not
doubles.

Any help is appreciated.
