different between serial and parallel running in reading pointzone

Dear foamer
I have problem with parallel simulation of new cases.

I have a pointZone as movingPointsZone that read by this code in a solver

Quote:

const pointZone& pz = fvMesh_.pointZones()[movingPointsZone_];
Info <<pz<<endl;

when I run serial, the output is same as pointZone in polyMesh/pointZone.
when I decompose mesh and run parallel, the output is very deference.

for example
in serial

Quote:

movingPoints

82464
(
131072
131073
131074
131075
131076
....
);

in parallel

movingPoints

(
23002
23003
23004
23005
23006
23007
23008
...
}

if I change decompose method

Quote:

movingPoints

15919
15920
...
}

in parallel running, the ids is all deference from pointZone, why?
Thanks
