I am new to Pega and I am trying to build some simple screens to prepare for a project. What I have done is created an external class map to a table in the database which will continue to serve as a system of record. I want to list one of the columns of this table as the values in a dropdown so the user can select it in order to bring up a specific record in the table and display it for editing. I have the activities built that will retrieve that data and should display it, but this dropdown is the current stumbling block. I've seen similar questions on here, but I have not seen any concrete steps on how to set it up. How do I take a column from an external database class and display it in a dropdown?
