InitContainerRadiusSearch with $TypeMasks::MarkerObjectType

Did anyone had any success using InitContainerRadiusSearch with $TypeMasks::MarkerObjectType?

Example:
I want to find all MissionMarker around my player so I use something like this:

InitContainerRadiusSearch(%obj.getPosition(), 100, $TypeMasks::MarkerObjectType);

But the resulting container is always empty...
Note that it's working if I use a different mask ("$TypeMasks::ShapeBaseObjectType" for example), so this part of my code must be OK.


I added "MarkerObjectType" to mTypeMask of MissionMarker (missionMarker.cc) but it still not working.

MissionMarker::MissionMarker()
{
   mTypeMask |= StaticShapeObjectType | StaticObjectType [b]| MarkerObjectType[/b];
   mDataBlock = 0;
   mAddedToScene = false;
   mNetFlags.set(Ghostable | ScopeAlways);
}
