Use SAML 2.0 to provide single sign-on authentication

Configure a SAML 2.0 authentication service to provide web single sign-on (SSO) convenience to product users in your enterprise. A one-click option lets you import Identity Provider (IdP) metadata and make use of automated certificate management.

User interface distortions in the Decision Manager portal

By default, the New Application wizard in Pega 7.1.6 configures new applications to include UI-Kit-7 in the list of application rulesets. This ruleset causes user interface distortions in the Decision Manager portal. Both applications created in previous maintenance level updates and applications created in Pega 7.1.6 that do not include the UI-Kit-7 dependency are not impacted by this known issue.

Workaround:

1. Open the application record.
2. In Application Rulesets, remove UI-Kit-7.
3. Save the application record.

Text Input control number type does not validate

When a Text Input control type is set to "Number" in the Presentation tab:

• Validation does not trigger and the field is blanked out when a user submits the form.
• If a value other than a number is entered, the browser sends an empty value, and the value is not validated.
• In the Clipboard, the field value displays as empty.
• If the field is required, the validation displays.

This issue occurs when using both the Chrome and Safari web browsers, and is a result of browser behavior for the HTML5 type=“number”. To fix this issue when using these browsers, do not use the "Number" type in Presentation tab of a Text Input control. Instead, the type should be set to "Text".

Need to run script before updating Multitenant systems

When updating or upgrading a Multitenant system from Pega 7.1.5 or 7.1.6 to Pega 7.1.7, if that system uses either an Oracle or a PostgreSQL database, you may encounter the error:

“Table must be empty to add column.”

The Multitenant architecture requires an additional column on a number of the PRPC database tables (“pzTenantID”). In Pega 7.1.7, two additional PRPC tables were tenant-qualified: pc_schedule_task and pr_index_schedule_task. The Multitenant column is added to these tables by the update/upgrade process. However, Oracle and PostgreSQL do not allow the addition of a non-null column to an existing table unless the table is empty, so updating or upgrading systems on those databases displays the error detailed above.

To avoid this error, before beginning the update or upgrade, it is necessary to run a script:

• Oracle — OracleMTupgrade.sql
• PostgreSQL — PostgresMTupgrade.sql

For updates, these scripts are located in the /scripts/ddl directory.

For upgrades, these scripts are located in the /Resourcekit/AdditionalUpgradeScripts directory.

User interface distortions in the Predictive Analytics Director portal

By default, the New Application wizard configures new applications to include UI-Kit-7 in the list of application rulesets. This ruleset causes user interface distortions in the Predictive Analytics Director portal. Applications created in maintenance level updates previous to Pega 7.1.6, and applications that do not include the UI-Kit-7 dependency, are not impacted by this known issue.

Workaround:

1. Open the application record.
2. In Application Rulesets, remove UI-Kit-7.
3. Save the application record.

Add additional columns to customized work history tables

The standard work history table, pc_history_work, contains two new columns that return the latitude and longitude coordinate location of the action that prompted the history. Mobile devices can display this location as a street address. If you have a customized work history table, add these two columns to it:

• <decimal name="pxLatitude" size="19" scale="9"/>
• <decimal name="pxLongitude" size="19" scale="9"/>

Unclear error message when saving shared class instance in tenant layer

If you attempt to save a shared class instance from the tenant layer, Pega 7 displays this message:

This record has x errors. Save Failed: There was a problem saving an instance of class: Error Code: <none> SQL State: <none> Message: <none>

You cannot save a shared instance from the tenant layer if that instance cannot be overridden.

Microsof Internet Explorer 9 (IE9) may display a script error when clicking a Help button

A script error may be displayed when clicking a Help button when script error notification is turned on in the browser. As a work around, uncheck the Display a notification about every script error option in the Advanced tab of the Options dialog box in Microsoft Internet Explorer 9.

Compare rule versions in a rule form

You can now compare different versions of rules from the Actions menu when you work within a rule form instead of using the Rule Compare utility. You can inspect changes that were made between versions directly on the rule form, make updates, and save any changes to the rule form.

For more information, see Rule version comparison within a rule form.

Performance improvement to BLOB support in Postgres databases

New tables that contain BLOB columns now use external storage instead of expanded storage for Postgres databases. This improvement applies to tables that are created during installation, upgrade, or during DDL and schema generation. Using external storage improves database performance.
