I would like to check in which order form prefill occurs in Transact Manager on form render:
...and in which order events are executed in-form
You may find information on the ordered form render events by reviewing the “Transact Services Guide” via Transact Manager. The documentation may be accessed under [Services > Transact Services Guide].
The ordered render events are found on the page: Transaction Processing Sequence (Which you may find in the index hierarchy on the left sidebar of the page).
You may read in detail about Form Prefill Data services and how they are executed by reviewing the information on the page “Form Prefill Data” in the same location as the Transact Services Guide.
