Why Use XPRESS?

Expressions are used primarily for the following Identity Manager tasks:

• Customizing the end-user and administrator forms. Forms use XPRESS to control the visibility of fields and to transform the data to be displayed and saved.

• Defining flow of control in Workflow. Workflow uses XPRESS to define transition conditions, which determine the order in which steps in the workflow process are performed.

• Implementing workflow actions. Workflow actions can be implemented using XPRESS. Action expressions can perform simple calculations, or call out to Java classes or JavaScript to perform a complex operation.

The expressions contained in these elements can be used throughout Identity Manager.
