After upgrading to Catalog v17.4, my requests using forms with dual lists do not save and display the dual selections after submission.
Additionally, when trying to approve these requests, the form validation fails due to the validation script not seeing any data.
CA Service Catalog v17.4 and up
Removing this from the Disable property of the lists/tables that were imported from the older versions of Catalog resolved the problem:
$(_.serviceoption.status() >= 0)
