Field
Description
Press the down arrow to select a property reference that identifies a single text value.
Alternatively, you can drag a property name from the lists of properties visible in the Application Explorer. Typically, this works for Single Value properties belonging to in the Applies to class of the current rule (or a higher class). If the container in which this field sits has a non-blank Using Page value, you can drag a Single Value property from within that embedded page property.
Click Open icon 
to review the property (if the reference is to an existing property in the Applies To class of this rule or a parent of that class). If the property is not found, the New dialog box for the property form appears.
You can reference properties on any page identified on the Pages & Classes tab, using the normal notation pagename.propertyname for pages other than the page corresponding to the Applies To class of the rule.
If this field is in a cell of a section that includes parameter declarations on the Parameters tab, you can enter the notation param.NAME here, to use a parameter value for the field, where NAME identifies a string parameter. Make sure that the NAME parameter is declared on the Parameters tab, and that your application provides a non-blank value for the parameter value in all possible situations where the section appears. See Sections — Completing the Parameter tab.
For a harness, the property generally must be on the primary page of the rule — the page corresponding to the Applies To key part of the rule. However, a section within the harness may have a different Applies To class, and that section can include properties from its own class.
If this field is always displayed as read-only, you can enter a linked property reference here, of the form .AAAA.BBBB, where AAAA is the linked property and BBBB is any property reference in the object identified by the value of AAAA as a key. For example, if the property AAAA has a value corresponding to a key of a Data-Admin-Operator-ID instance, then .AAAA.pyUserName presents that Operator ID's full name. This allows values from that object to appear (read-only) in the run-time display, though your processing does not explicitly load the object onto the clipboard.
Select to use the default label for the property or specify your own label. select or create a label.
Use SmartPrompt to select a field value rule if you plan to localize the text. See About the Localization wizard.
Optional. Enter a constant value for the property value, a property reference, or an expression, to be used only when the user form or flow action form appears in read-write mode rather than read-only mode.
Choose a default value that speeds data entry. When the system renders a harness or section in read-only mode (for example because the read-write mode requires a privilege that the current user does not hold), the default value does not appear, because data entry is not permitted.
Select None if you do not want to display placeholder text.
Select Other if you want to display a hint or instructional text in the field. The text disappears when the user enters a value. If the user does not enter a value, the placeholder text reappears when the field loses focus.
Specify a tooltip to display when the user hovers the mouse pointer over the control. You can press the down arrow to select a property value or type the text that you want to display as the tooltip.
As a best practice, start the sentence with a verb, either in the imperative ("Enter price of item here") or as an infinitive ("To cancel the order, click here").
Use SmartPrompt to select a field value rule if you plan to localize the text. See About the Localization wizard.
To control the visibility of the container, select one of the following:
- Always: Always visible.
- Condition (expression): The region is visible under the specified condition. In the field that displays, select a condition or click the Gear icon to open the Condition Builder. You can define a simple expression based on the comparison of a pair of constants, properties, or both, combined by Boolean operators, such as .Color="Red". You can combine the expression with a when condition rule or another expression using the && and || operators.
- Condition (when): Tthe region is visible under the specified condition. In the field that displays, select a when rule. Click the Open icon to create a new when condition or review an existing when condition.
If this section is to become part of navigation in a composite portal, you can make the header visible only when a specific space is the current space. Enter an expression here similar to the following:
pyCurrentSpace=="ASpaceName"
Then, select the Run visibility condition on client check box.
Select to disable the text input:
- Never: never disabled
- Always: always disabled
- Condition (expression): the text input is disabled under the specified condition. In the field that displays, select a condition or click the Gear icon to open the Condition Builder. You can define a simple expression based on the comparison of a pair of constants, properties, or both, combined by Boolean operators, such as .Color="Red". You can combine the expression with a when condition rule or another expression using the && and || operators.
- Condition (when): the text input is disabled under the specified condition. In the field that displays, select a when rule. Click the Open icon to create a new when condition or review an existing when condition.
Appears only for fields in cells on flow actions and sections. Select to require that when the form appears at runtime in read-write mode, users cannot successfully submit the form if the field is blank.
Selecting Required marks the label for this field with an orange asterisk 
when the flow action form appears in read-write mode. (The asterisk also appears if the Label control's Value For field is not blank and the Label control's Required box is checked.)
For sections, checking this box enables client-side format validation when this section is part of a harness form that has the Enable Client Side Validation box selected on the HTML tab. At runtime, users who leave this field blank and submit the form are notified immediately that the field is required; the form is not transmitted to the server.
Optional. If authorized, you can provide a unique Test ID for use in your test suite in order to support better automated testing against any Pega application.
When creating a control that supports Test ID, the Test ID field is initially blank. Use a combination of numbers, letters, and underscores, or click the Generate ID button to create a time stamp as a unique ID. The attribute data-test-id is then generated for the selected element.
When you save an existing section, any supported controls that do not have a Test ID will have one automatically generated. You can override these with a custom ID at a later time.
Once generated, you can view your Test ID in HTML or display it in the Live UI panel.
You also have the option to have all controls that support Test IDs in a ruleset updated in bulk.
A standard, out-of-the-box developer role, PegaRULES:SysAdm4, includes the privilege for Test ID. To disable Test ID for this role, modify the pxTestID privilege.
