Parameter editing screen

Fields	Remarks
Parameter	Unique identifier for the parameter; must respect nomenclature and be limited to 30 characters (required field) Application parameters such as FORM_FIELDS_READONLY are available through the Other parameters button. This is commonly associated with the name/ID of the form field. Note: Parameter names should respect the following XML naming rules: They should begin with a letter or an underscore They should contain only letters, digits, hyphens, underscores, and periods They should not contain spaces They should not begin with the letters XML in any case (e.g. xml or Xml) For more information, see https://www.w3schools.com/xml/xml_elements.asp.
Browse	This button is only visible for actions that have at least one default application parameter defined
Direction	Parameter direction: IN: When the action is instantiated, the value of the parameter is initialized with a text, or the value of a macro or process data. OUT: When the action is being closed, the value of the parameter is stored in a process data value. INOUT: When the action is instantiated, the value of the parameter is initialized with a text, or the value of a macro or process data, and then, when the action is being closed, the value of the parameter is stored in a process data value.
Send the value of	The IN value to send to the parameter Depending on the type of data to be associated, this value can be process data, a macro or a freeform text value.
Receive the value into	The process data where the OUT value of the parameter is stored
Save button	Save changes
Save and close button	Save changes and close the screen
Add button	Save the current parameter and display a blank form to add a new parameter
Delete button	Allow the deletion of the current parameter
Close button	Close the screen without saving

Editing parameter expressions

WorkflowGen supports VBScript and JavaScript expressions in action parameters, which can be created either directly as action parameter values, or in TEXT type process data mapped to action parameters as IN values.

Creating an expression as an action parameter value

1. Under Send the value of in the Edit parameter panel, choose a text and place the expression in the text area.

2. Next to Scripting, check Enable, then choose either JavaScript or VBScript.

Creating an expression as a TEXT process data

1. In the Edit data panel, place the expression in the Default value text area.

   Tip: Click the pencil icon next to the Default value text area to open a larger text editor that includes JavaScript and VBScript syntax highlighting.

2. Specify the language either on the Mapping tab in the Form Designer, or in the Edit parameter panel:

   • In the Edit parameter panel, check Enable next to Scripting, then choose either JavaScript or VBScript.

     OR

   • On the Mapping tab in the Form Designer, choose the data's Value IN button, select the expression from the Data drop-down list, check Enable next to Scripting, then choose either JavaScript or VBScript.

All WorkflowGen macros (except notification macros) are fully supported in both languages and are enclosed by < >(e.g. <WF_PROCESS_INST_ID> for the request number).

In both languages, the expected result must be either a number, a string, or a date.

Examples

This example would return the request number plus 5 in both JavaScript and VBScript:

<WF_PROCESS_INST_ID> + 5

No return keyword is needed for expressions, with the exception of JavaScript inside a function. However, you cannot directly return the function; instead, it must be invoked and must return something like the following example, which would get tomorrow's date:

(function(){
    var today = <WF_SYSTEM_DATE>;
    var tomorrow = new Date();
    tomorrow.setDate(today.getDate()+1);
    return tomorrow;
})();

OR

function test(){
    var today = <WF_SYSTEM_DATE>;
    var tomorrow = new Date();
    tomorrow.setDate(today.getDate()+1);
    return tomorrow;
}
test();
