  • detail trigger of Field
  • help trigger of Field
  • menu trigger of Field, Entity, or Component
  • receiveMessage trigger of Component
  • pulldown trigger of Component

It is not allowed at the most generic level of these triggers, thus not in:

Description

Use the $callup function to call the same trigger at the next level up in the call-up hierarchy , or the next available level up, if applicable.

Call-up Hierarchy

Callup hierarchy for triggers that support the $callup function

 

Upon return from a $callup call, the value of $status is whatever it was at the moment the called-up trigger returned.

Using $callup

The following example shows how the $callup function can be used to call the entity-level detail trigger from a field-level detail trigger:

; The Script container of field FLD.ENT.MDL
trigger detail
  variables
    string vStatus
  endvariables
  putmess "This is the field-level detail trigger"
  vStatus = $callup
  putmess "vStatus is %%(vStatus), $status = %%($status)"
end
;----------------------------------------------------
; The Occurrence Script container of entity ENT.MDL
trigger detail
  putmess "This is the entity-level detail trigger"
  $status = 321
  return 123
end

When the detail trigger of FLD.ENT is activated, the message frame will contain this output:

This is the field-level detail trigger
This is the entity-level detail trigger
vStatus is 123, $status = 321
