Value section (variable definition)

The second section of the Variable Definition task properties form is labeled Value. The purpose of the Value section is to specify the source of the initial value for this variable. The possible values are:

Clear

The initial value of the variable is empty.

From Task

When you select the From Task radio button, the system presents a drop-down list containing the compatible preceding task steps whose result type (module and business object) match that of the variable. Choose a task step from those presented.

From Expression

When you select the From Expression radio button, you use the expression editor to define how to derive the value for the variable. At runtime, the system evaluates the expression and returns an array of record Ids. If an expression does not evaluate to any record or if an error is encountered when evaluating the expression, an empty array is returned.
