The JS7 - Workflow Editor allows variables to be declared. Clicking in the workflow editor panel will display the workflow properties where variables can be added:

ExplanationsExplanation:

• Order variables are declared by specifying a name and data type.
  • If no default value is added then the order variable is mandatory, i.e. all orders have to specify a value for the variable.
  • If a default value is added then
    • the order variable is optional, i.e. orders can specify a value and otherwise the default value will be used.
    • the final data type can be added that prevents the variable from being modified later on in the workflow.
  • Default values accept constant values and JS7 - Expressions for Variables.
• Any number of order variables can be declared.

For order variables of data type "String" the workflow editor offers the following operations from the Image Added icons:

• The Image Addedicon invokes facet entry mode.
• The Image Added icon invokes the list entry mode.
• The Image Added icon invokes the editor entry mode for values of variables

Editor Entry Mode

Clicking the Image Added icon brings up a popup window that offers more space for character input of variables:

The window size will adjust automatically if more characters are entered.

• The Image Added icon can be used to maximize the window size.
• The Image Added icon can be used to change the window length.

List Entry Mode

The Image Added icon invokes the list editor that is used to offer a list of values from which a user can select when adding an order to the workflow.

Facet Entry Mode

The Image Addedicon invokes the facet editor. Facets are regular expressions that are used to check user input to match a given pattern.

Regular expressions can be complex and lengthy. The facet editor offers the Add from Favorites link to select values from JS7 - Favorites.

In the Workflows view when an order is added user input is checked like this:

• Input that does not match the regular expression is denied and the order cannot be submitted.
• An information icon displays a tooltip with the message that has been added to the facet.
