Steps to Reproduce

1. Create a section containing a property with a DateTime control
2. Set the default value with the current DateTime function as below:
   
   @(Pega-RULES:DateTime).CurrentDateTime()
    
3. In the Presentation tab, use the Edit option as Read-Only. In the Read-Only value use 'Constant' and set the same function as below:
   
   @(Pega-RULES:DateTime).CurrentDateTime()
    
4. On the UI, the DateTime value did not display. Instead, the function displays as a string.

Root Cause

However, when the above configuration was run in the non-Template mode, the control fetches the value from the property that is bound to the control rather than displaying the Constant value. This property which is bound to the control may possess the current DateTime value always. Hence, the DateTime value is displayed in the non-Template mode. However, in the Template mode, the control picks and displays the mentioned constant string (in this case, @(Pega-RULES:DateTime).CurrentDateTime()).

Resolution

1. In the Presentation tab, configure 'Read-only (always) with Property Value'.
2. In the General tab, bind a DateTime time property reference and populate this value using a data transform to have the current DateTime (data transform > Set {propertyVariable} to @(Pega-RULES:DateTime).CurrentDateTime()').
