Prepare: check unsaved data

Triggering event – Abstract

This triggering event is only available at the form level and is triggered before the data is written back from the form to check for changes in the entity.

The data is not written back to the entity until all behaviour and actions have been processed. This also means that when the data is changed in the context of this triggering event, there is also a 'Discard changes?' Please note the user would be consulted.

NOTE◄ If too costly/slow behaviours or actions are executed, the whole form can become sluggish!
