11.8. Assignment
The assignment mechanism allows you to assign a value to an object, such as a variable, before or after the particular Element is executed.
When defining assignment on an Activity Element, the value assignment is performed either before or after Activity execution. If the assignment defines mapping to a local variable, the time when the assignment is performed depends on whether the local variable is defined as an DataInput or DataOutput item.
For example, if you need to assign a Task to a user whose ID is a Process variable, use the assignment to map the variable to the parameter ActorId.
Assignment is defined in the Assignments property in case of Activity Elements and in the DataInputAssocations or DataOutputAssociations property in case of non-Activity Elements.
Note
As parameters of the type String can make use of the assignment mechanism by applying the respective syntax directly in their value,
#{userVariable}, assignment is rather intended for mapping of properties that are not of type String.
