You can define whether parameters and attributes are read-only constants or writeable variables. You can also set limitations on the values that users can provide for input parameters.

Setting certain parameters to read-only allows other developers to adapt the workflow or to modify it without breaking the workflow's core function.

Prerequisites

Complete the following tasks.

■

Create the Simple Workflow Example.

■

Create the Schema of the Simple Workflow Example.

■

Define the Parameters of the Simple Workflow Example.

■

Define the Simple Workflow Example Decision Bindings.

■

Bind the Action Elements of the Simple Workflow Example.

■

Bind the Simple Workflow Example Scripted Task Elements.

■

Define the Simple Workflow Example Exception Bindings.

■

Open the workflow for editing in the workflow editor.

Procedure
1

Click the General tab at the top of the workflow editor.

Under Attributes is a list of all the defined attributes, with check boxes next to each attribute. When you select these check boxes, you set attributes as read-only.

2

Select the check boxes to make the following attributes read-only constants:

■

progress

■

pollRate

■

timeout

■

smtpHost

■

fromAddress

■

subject

You have defined which of the workflow's attributes are constants and which are variables.

What to do next

Set the parameter properties and place constraints on the possible values for that parameter.
