Providing values from two different sources

Best practices
1

I have a regular component on a form - let’s say it’s a birth date.
This form is a manual task in a process.

By default, when a user opens this form, I want this component to be already filled with a date from a previous form (from a different manual task).

However, if such date is not present (was not entered on a previous form) I need the system to calculate the birth date from PESEL.

Only when both values are empty (the date from the previous form and the PESEL value) I want the user to fill the date manually.

So what I eventually need is a cascade:

  • if present, use the previously entered birth date
  • else, if PESEL is present, calculate birth date from PESEL
  • if both are empty, let the user fill the date manually.

What is the recommended approach to this problem?

I recommend using technical fields in such cases.

I assume you have two fields: date of birth and PESEL, and the date from the previous request will come as an input parameter to the form and will be mapped to a session variable.

So, first of all, I would add a technical field with a script attached that calculates the date of birth from the PESEL as timestamp.
Then I would create a technical field that will map the first non-empty value from the list: date of birth from previous form and date of birth from PESEL.
Finally, I would map the technical field mentioned above to the date component via “Źródło danych z innego pola” and set an active condition to check if the technical field is empty.
Remember to add listening where required

Thanks!
But… do I have to do it manually for all 200 fields?
Maybe you could come up with some kind of automation, or a ScriptCode ?

I think you’ve confused the thread with this: How can I fill a form with values read from a different form

Damn you’re right!
They overlap, in a way, but yes.
Thanks for your answer.
