Unlike stream action attribute expressions, context parameter expressions can evaluate to a list of values as well as single values.

The context parameter expressions can refer to:

  • data from the dashboard, view or form from which the action was initiated
  • $-variables used in other context parameter expressions on the same action.

Use the notation:

  •  to refer to values on a form:
       _prompt.<Form Field Name>     to
  • to refer to values on a formattributes of selected records:
       <View name or alias>.<Attribute name or alias>   to refer to attributes of selected records 

The expression can include the message functions debug(message), info(message), warning(message), and error(message), which write messages  to the system console logs. Remember that error(message) function stops the action from completing.
