empty table for output parameter "column"

[wee lee]

Hi,

I am testing pydf 1.2.1 and have an issue.

I created 3 input parameters and 3 output parameters, each of them is type of table, column and value as indicated in the names.

input: intable, incol, invalue

output: outtable,outcol,outvalue

Parameter table and value are working fine for both input and output. However, output parameter of type column produces no data.

Please see attached dxp and png for details.

Thanks.
