Determining if child records are created

[kklosson]

I'll use a metaphor:

During the creation of a supervisor object, the user can select one or more existing employees (peers) to assign to the supervisor. As a rule on the Supervisor, I want to determine whether any employees have been assigned and if so, send an email notification to each. I can't figure it out any syntax that works.

Not workable but expresses the idea:
IF EXISTS Employee IN Supervisor.Employees THEN

Since the object may not be committed to the database at this point, I am unsure if this is feasible. It's probably really easy like all things in AIM and I'm just over thinking it.

Sounds like you want to check if the Supervisor instance IS NEW + if Supervisor.Employees IS DEFINED.

If both of these conditions exist, you want to find the Employees in Supervisor.Employees and send email the email.

Perhaps try

IF EXISTS Employee WHERE Employee IN Supervisor.Employees THEN
