When using nested variables, in TDM Portal Self Service Catalog Tile, multi-select default values won’t be displayed

Products

• CA Test Data Manager (Data Finder / Grid Tools)

Issue/Introduction

We have created nested variables in a Generator, to populate default values to be used in a Find & Reserve Tile in the Self Service Portal, to populate the default values used by the Data Reservation form,
but the default values are not getting resolved in the form and therefore the values are not showing up as expected.

Environment

Test Data Manager
TDM Web Portal

Resolution

As long as you are working inside the Generator, we are able to resolve and populate the values of the nested variables. 
However, the Self Service tiles are outside the Generator context, and Portal does not know which Generator to use to populate the default values.
As a workaround, you will need to hard code the default value in the SQL request.
