We have a requirement to display multiple Date fields being returned from an API as a read only value. We found that whenever source system has an empty value in Date field, the Pega Target property is setting the value as 01 Jan 1970. Based on the suggested solution we found in PDN for this issue, we skip the property set if the source property doesn't have a value. But this approach displays Date as '-------' in the UI. Any suggestion to resolve this? Target property is of type 'Date' displayed in custom format of dd MMM yyyy.
