Declaring variables for client-side human services

For each client-side human service that you create, you must declare variables to capture the data that steps or activities in that service flow use.

To add a private, input, or output variable to the client-side human service, complete the following steps:

1. Open your client-side human service in Process Designer.
2. In the Variables tab, click the plus sign next to Input to add a new input variable.
3. In the Details section:
   1. Type a variable name in the Name field.
      Note: Variable names start with a lowercase letter, with subsequent words capitalized, for example: myVar. Do not use underscores or spaces in variable names. Variable names are case-sensitive.
   2. Click Select next to Variable Type to select the type of the variable from the Select Library Item list. Custom business objects that you created are also listed. If you want to create a new business object, click New and complete the wizard steps.
      Note: Client-side human services do not support business object instances that reference themselves. For example, the following JavaScript generates an error when used inside a client-side human service:

      tw.local.myVariable= {};
      tw.local.myVariable.pointer= tw.local.myVariable;

   3. Optional: Type a description of the variable in the Documentation field.
   4. Optional: If you want your variable to be an array, select Is List.
4. Save the configuration.
5. Iterate through steps 2 to 4 to add output and private variables to the client-side human service.
