PeopleCode - Person Update using CI_PERSONAL_DATA

Hello,

I am working on rest services to update employee data within PeopleSoft HCM (v8.60). I am using the CI_PERSONAL_DATA component interface to work with the employee data. I am successfully able to create a new person with this process.

However, I am getting stuck when updating an existing employee. I can pull in the existing employee and change top level properties. However, trying to make changes to collection items such as existing names and addresses fails. When setting the name for instance, I can set the property to the new name, and on the very next line try outputting the newly set value, and it will still show the old value.
