Error when pass number array to composite datawindow

Hi All,

PB12.5 here.

I have a datawindow which retrieve argument is a number array.

When I tried to add this datawindow to composite datawindow, found that there is no option to set number array, as below, so, I have no choice and select "number" as type, but it will hits error "DataWindow Error - Retrieve argument 2 does not match expected type.", when I try to retrieve data.

I would like to know how to set or pass this number array to composite datawindow.

Kindly advise.

Thank you.

BR,
