The Properties window of the Assign element, invoked by right-clicking the element and choosing Properties, contains two properties:
Name: The name of the element.
Validate: Specifies whether the JavaScript (Assign) activity validates any variables modified by the activity. When the value is “yes” , the activity will validate all of the variables it modifies. If the validation fails because one of the variables is invalid to its corresponding XML definition, then a standard fault bpel:invalidVariables is thrown. The default value is N/A.
Documentation: User documentation attached to the element. This documentation is included with the source code of the BPEL process and can be extracted and included in a report.
