• form.load : This event occurs when a form or workflow step loads for the first time. It is useful for setting default values via rules that you need to be set before the user starts interacting with the form. 
• form.unload : This event is true when users click the form's Submit or a workflow's Continue button. It is useful for setting control values just prior to the execution of the form's Doc Actions and Form Actions. If you have a rule in your form that changes any control(s) after clicking Submit, thereby making the form invalid, the form will no longer be submitted and the invalid form will redisplay. Form and Document actions will not execute,  PDFs are not generated, invalid controls become highlighted as expected and form.unload output displays in the Debug Console. This prevents an invalid xml for a successful submission from being created and only applies to forms.
  
• form.positionUpdated : This event is used for the Geolocation feature. You can fire a rule using this special identifier every time the position is updated.
• form.activate: This event indicates that a workflow has navigated to a step. If form.activate is true, the workflow just moved to a step. Use the Execute a Rule on a Specified Workflow Step example to determine what step that is.
  
• form.deactivate:  This event indicates that a workflow has left a step. If form.deactivate is true, the workflow just left a step. Use the Execute a Rule on a Specified Workflow Step example to determine what step that is.

Every control has a Properties icon. Click the "+" to expand the Properties. You will see a list of all the properties that are applicable to this control. Note that even the "form" itself has a Properties icon which shows that the form has form.load and form.unload properties. LoanNumber is a quantity control and thus has all the properties you expect for this control type such as LoanNumber.required, value, visible, etc.

Refer to 1069258771 Rule Editor Functions for an alternative method of composing rules within the rules editor.

When you are designing a form/workflow with many objects and a lot of business rules, reduce the number of page reloads when switching between the designer view, rules view, and the test view by clicking the  save and test icon. Save and Test checks for Rule errors before the test popup displays. If rule validation errors are detected, the designer is notified and given the option to correct them before the Test popup is displayed.

...

The validator also supports global directives. Use the global directive to identify additional global objects and functions defined in the execution environment and made available to the rule for which it is not appropriate to include a var statement in the rule code itself. One directive can be used to list all additional globals on a single line. Currently, there are no known cases requiring the use of the global directive.  

Rule Editor Functions

The Rule Validator includes an enhanced editor designed to provide an easy experience when developing rules. The rule editor box includes the following features:  

Features	Description
Line Numbers	Line numbers in the rule code editor make it easier to correlate reported validation errors with the line of code.
Bracket auto close	Type a {, ( or [ and the closing bracket is automatically inserted.
Match Bracket	Place the cursor on a bracket and both it and the matching bracket are shown in a matching distinctive color (green).
Syntax Hi-lighting	JavaScript syntax hi-lighting with keywords, variables, comments, etc. shown in distinctive colors.
Auto Indent	New lines are auto-indented according to generally accepted code formatting rules.
Code Folding	Bracketed code blocks (functions, if-then-else blocks, etc.) are collapsible. Click the arrow immediately to the right of the line numbers to collapse/expand code blocks.
Full screen edit mode	Expand the editor to full screen mode if you need more space to work. Click the "double arrow" expand icon (directly above the editor box) or press F2 when your cursor is inside the Rule box to expand to full screen. The ESC key returns you to small window mode.
Auto Complete/Hinting	When composing a rule, the designer can pick from a list of available frevvo controls and their properties directly within the rule editor. The pick list is context sensitive and will behave differently based on where the cursor is located when it is invoked. When on a blank space or immediately following an open bracket/brace, it can be manually invoked using Ctrl-Space to bring up a list of controls. Typing a dot (.) immediately after a frevvo control name or after the index ("[i]") that follows a control name will automatically bring up a context-sensitive pick list of properties applicable to that control for selection. You can type the first letter of the item you are looking for and the property starting with that character will be highlighted in the list. Continue typing and the matching options will progressively narrow to the characters typed. Double click your choice using the mouse or press the Enter key to select an item. Any other key dismisses the pick list. . See the example 1069258771 AutoComplete/Hinting Example.
Help	The help icon displays a small help window listing the hotkeys described above - (F2, ESC, and Ctrl-Space)

...

Rule execution can be profiled to determine how much time each rule takes to execute. This can help you tune and improve performance in forms that use a lot of business rules. To turn on profiling in the log files set the rule-debug=INFO or higher. See 1069258771 Rule Debugging for setting log levels. Profiling output is also displayed in the Debug Console.

Reusing Data from a Web Service

The example above uses the database connector, which returns a clean json that doesn't cause any problems when it is copied into a text field. The json returned from other services might include extra spaces or other characters and might require trimming. This can cause an error such as 'SyntaxError: Unexpected token in object literal'.

You may need to add this code, which removes spaces from the json string, to your first rule:

​var json = http.get(requestUrl);
jsonUserData.value = json.replace(/[\n\t\r]/g,"");

...

1. FirstName.value - only for parameters bound to a control in your form.
2. {FirstName} - only for parameter used in http get 1069258771 Templatized URIs.
3. _data.getParameter('FirstName') - if used anywhere else in a rule other than a URI.

...

LDAP supports both the standard subject attributes and custom attributes. When a user is successfully authenticated by the LDAP security manager, frevvo automatically retrieves Last Name, First Name and Email Address for this user from the LDAP server. You can retrieve custom attributes in addition to the standard ones from Active Directory and pull the data into your form/workflow using frevvo business rules. 

Rules can use 1069258771 Built-in Methods methods to populate controls on a form/workflow with the information for the logged in user. The rules use the frevvo  _data.getParameter syntax, For example, the business rule shown fills the respective form fields with the First/Last Names and Email Address of the logged in user. 

...

Attributes with more than one value are also supported. For example, The carLicense attribute can return multiple licenses. You can write a rule to populate dropdown options with those values. Make sure the carLicense attribute is added to the custom field on the LDAP Configuration screen and of course, there are multiple carLicense attributes, each one containing a different value for the dropdown options, set up for appropriate users on the LDAP server.

...

If these methods are used in rules a the designer will see a message in the 1069258771 Debug Console urging that the methods listed 1069258771 Date and Time Methods be used instead.

...

Here is a snippet of debug console output. The frevvo.log() message Event type displays as "CUSTOM". In this example the rule called the method frevvo.log('ERROR', 'Loading tenant roles...'); The message appears in red because all ERROR level log messages automatically are colored red.

See the 1069258771 Debug Console topic for full details of all the console output information.
