Obtaining Input Parameters from Users When a Workflow Starts
If a workflow requires input parameters, it opens a dialog box in which users enter the required input
parameter values when it runs. You can organize the content and layout, or presentation, of this dialog box
in Presentation tab in the workflow editor.
The way you organize parameters in the Presentation tab translates into the input parameters dialog box
when the workflow runs, and in the dialog box that opens when you run a workflow from a Web view.
The Presentation tab also allows you to add descriptions of the input parameters to help users when they
provide input parameters. You can also set properties and constraints on parameters in the Presentation tab
to limit the parameters that users provide. If the parameters the user provides do not meet the constraints
you set in the Presentation tab, the workflow will not run.
IMPORTANT The use of OGNL expressions in workflow presentations is deprecated as of Orchestrator 4.1.
Using OGNL expressions in workflow presentations is not supported in releases of Orchestrator later than
4.1.

Creating the Input Parameters Dialog Box In the Presentation Tab on page 41
You define the layout of the dialog box in which users provide input parameters when they run a
workflow in the Presentation tab of the workflow editor.
n
Setting Parameter Properties on page 43
Orchestrator allows you to define properties to qualify the input parameter values that users provide
when they run workflows. The parameter properties you define impose limits on the types and values
of the input parameters the users provide.
Creating the Input Parameters Dialog Box In the Presentation Tab
You define the layout of the dialog box in which users provide input parameters when they run a workflow
in the Presentation tab of the workflow editor.
The Presentation tab allows you to group input parameters into categories and to define the order in which
these categories appear in the input parameters dialog box.
Presentation Descriptions
You can add an associated description for each parameter or group of parameters, which appears in the
input parameters dialog box. The descriptions provide information to the users to help them provide the
correct input parameters. You can enhance the layout of the description text by using HTML formatting.
Defining Presentation Input Steps
By default, the input parameters dialog box lists all the required input parameters in a single list. To help
users enter input parameters, you can define nodes, called input steps, in the presentation tab. Input steps
group input parameters of a similar nature. The input parameters under an input step appear in a distinct
section in the input parameters dialog box when the workflow runs.
Defining Presentation Display Groups
Each input step can have nodes of its own called display groups. The display groups define the order in
which parameter input text boxes appear within their section of the input parameters dialog box. You can
define display groups independently of input steps.
