You cannot pass an array property this way.
You can either

1. pass the object and let the function called refer to the object.array, or
2. copy the object.array to an array var, e.g.

Dimension laPass(ALen(this.aGroup,1), ALen(this.aGroup,2))
ACopy(this.aGroup, laPass)
thisform.oBCSUtilities.aColScan(@laPass, cClientGroup, 1)
*-- copy it back to the array property
Dimension this.aGroup(ALen(laPass,1), ALen(laPass,2))
ACopy(laPass, this.aGroup)

If you use the 2nd approach, the aColScan method can be used from anywhere, just by passing in an array.
