- What to do instead

The problem is, that too many subscribers don't exit when IsHandled was already passed as true.

I recently saw this #msdyn365bc function GetDate() in table "Sales Line". Why setting the default values for IsHandled and ResultDate? These vars are defined as local vars, so will always have these default values when started. For clarity?

nit nit nit ;-)

I've just discovered that Microsoft does not have a naming standard for the boolean variable for the (Is)Handled pattern. I thought it was only IsHandled, but also Handled is used across all repos.

I think this evolved when Microsoft started to mass-insert events on request. Mistakes (such as forgetting to reset IsHandled between two events) happened quite often.
