Can anyone think of a reason why onAfterLoad/onBeforeLoad do not fire when entering a form but onDestruct does when leaving a form.
I’m writing some code using webix jet, and the events fire in one form but not in any of the others.

Hello!
onAfterLoad is really fires after data loading is complete
onBeforeLoad fires immediately before data loading has started
onDestruct occurs when component destroyed and can be used to free memory or delete the related objects.
