Advanced options for a harness

Applicable to UI-Kit applications

You can define how your application generates HTML code to save processing power and improve the user experience. Each time you save a harness, Pega Platform generates source HTML. By understanding the advanced settings in a harness rule, you can customize HTML to meet the needs of your application.

Advanced options

The following table lists the settings that govern HTML creation in a harness rule:

HTML settings in a harness

Setting Description
Enable client side validation

Causes the application to validate the input that the user enters in a field even before the user submits the entire form.

You can use this feature in applications where users enter data, such as text or dates, by typing rather than selecting. Client-side validation detects and marks invalid input earlier, and it generates less network traffic.

Standard client-side validation scripts are in the webwb.CSValid.js text file rule. For localization purposes, the corresponding error messages are in the CSValid HTML fragment rule . You can add custom client-side validation scripts or error messages on an application-wide level by overriding the UserWorkFormHTML fragment rule , which isin the fragment rule WorkFormStandard.

Enable expression calculation

Causes the application to recalculate the target properties of a declare expression rule and properties that are involved in constraints rules.

The system updates the display when the user focus leaves the input field for a property. For more information, see More about Declare Expression rules.

Portlet compliant

Generates portlet-compliant HTML that a portal server can display. Portlet-compliant HTML meets the requirements of Java Specification Request 168, which defines the portlet standard.

You can send a portlet-compliant harness form to an external portal server through Service Portlet rules and display it in a portlet window. A harness is portlet-compliant only when its sections are also portlet-compliant.

The rule type Service Portlet is deprecated. Use Pega Web Mashup instead.

The Work-.SimpleConfirm standard harness is an example of a portlet-compliant form.

Localize

Indicates that the application can localize the text in this harness. At run time, if your application contains a translated ruleset for a user locale, the harness displays the text in the relevant language.

This check box is available only when you set Generate For to JSP.

For more information, see Localizing your application.
Do not display dirty warnings

Prevents the harness from displaying warnings about unsaved work.

Create skeleton

Generates a placeholder UI when the application loads the harness.

Work area

Designates the harness as an area where documents open for processing in the application.

If you select the Work area check box, the UI displays the Do not display in channel content list check box.

Document type

Overrides the document type for the harness. By default, the application rule determines the document type.

You can select one of the following document settings:

Inherit from application rule
Uses the document type set on the application rule. The default for new applications is HTML 5.
HTML 5 (standards mode)
Renders in standards mode
None (quirks mode)
Renders in quirks mode.
IE document mode

Determines how the harness uses document compatibility mode in Microsoft Internet Explorer. You can select one of the following document settings:

Pega default
Does not support compatibility mode. The browser does not emulate older versions of Microsoft Internet Explorer.
None
Does not support compatibility mode. The browser does not emulate older versions of Microsoft Internet Explorer.
Other
Provides you with tools to set the X-UA-Compatible Mode on the harness to ensure that the application can emulate an older version of Microsoft Internet Explorer.
Enable client-side template UI Sets the template-based rendering of the UI. You can select one of the following settings:
Pega default
Does not use a template-based UI.
Yes
Turns on a template-based UI, which runs on desktop and mobile platforms and in offline mode.
No
Does not use a template-based UI.
ID Sets an alphanumeric ID for this layout for use in JavaScript functions.

The system attaches the ID attribute to the <body> HTML element of the harness.

HTML Source

Displays a read-only version of the harness in HTML.

At run time, Pega Platform uses stream processing to evaluate the JSP tags and the source HTML in the context of the current clipboard contents and static files. The HTML references properties and other rules, such as HTML fragment rules, HTML rules, controls, and sections.
