Published Release Notes

Extension attributes are not supported in PMML models

Models in the Predictive Model Markup Language (PMML) format version 4.3 that contain extension attributes with the x- prefix are not valid. These extension attributes are deprecated; you must use extension elements instead. In addition, if the output type of any output field in the model is set to FLOAT, change it to DOUBLE.

For more information, see PMML 4.3 - General Structure in the Data Mining Group documentation.

The Upload responses action is not supported for adaptive models with customized context

A default instance of the Adaptive Model rule contains five model identifiers (.pyIssue, .pyGroup, .pyName, .pyDirection, .pyChannel) that are used to partition adaptive models. If you add other identifiers in your Adaptive Model rule instance, you cannot upload responses to this instance with the Upload Responses wizard and the following error is displayed: The Flow Action post-processing activity pzUploadCSVFile failed: Cannot parse csv file.You can still train such adaptive models with data flows.

For more information, see Training adaptive models in bulk with data flows, Model context, and Uploading customer responses.

Limited question and answer formats in new surveys

Complex questions and some answer formats for simple questions, such as attachment, are not supported by the new surveys that you create. Although you can create stand-alone questions in your survey library that use these formats, you can add these questions to legacy surveys only.

For more information about supported answer formats, see Answer formats for questions in a survey.

The worklist appears to be empty when you go back from an opened case in an offline-enabled mobile application

In a Pega^® Platform offline-enabled application, when you go back to the worklist from an opened case, the worklist appears to be empty even though it contains cases. This issue will be fixed in the next release of Pega Platform. Only portals that use the key principles and design of the pyCaseWorker portal are supported in offline-enabled applications.

For more information, see Offline mobility guidelines.

Browser unresponsive when logging in to Designer Studio

The What's new in 7.4 widget on the Designer Studio home page uses WebGL to render its background animation. If your browser is running on a virtual machine without hardware acceleration, your browser might become unresponsive because of this widget. Click the Hide this until next release button to remove the widget. At your next login, the widget will not be displayed.

Use fast processing option does not work

The Use fast processing option on Connect REST and Service REST rule forms does not work unless you obtain the HFix-43000 hotfix from Global Customer Service.

Use the following data model guidelines when using fast processing:

• The JSON property names and the clipboard property names must match.
• The JSON tree structure and the clipboard tree structure must be similar.
• The scalar arrays in JSON must be mapped to the clipboard as page lists.
• Multi-dimensional arrays must be mapped into page lists of page lists with the same embedded property names.

​In addition, page groups, value groups, and Java objects are not supported by fast processing.

Upgrading Adaptive Decision Manager data mart tables might fail

Issue: Upgrade from 7.3 to 7.3.1 fails if the data contained in the pxInsName column of the PR_DATA_DM_ADMMART_PRED_FACT table is longer than 128 characters.

Reason: During the Pega Platform™ upgrade from 7.3 to 7.3.1, data in the Adaptive Decision Manager (ADM) data mart tables is migrated from the PR_DATA_DM_ADMMART_PRED_FACT table to the PR_DATA_DM_ADMMART_MDL_FACT table. In Pega 7.3.1, ADM uses only the PR_DATA_DM_ADMMART_MDL_FACT table where the pxInsName property can store values that are 128 characters long. In Pega Platform 7.3, the pxInsName property in the PR_DATA_DM_ADMMART_PRED_FACT table can store values that are 255 characters long. If the pxInsName property contains values that are longer that 128 characters, the upgrade fails.

Resolution: Issue an ALTER TABLE statement to change the pxInsName column size to 255 characters and resume the upgrade. For example:

ALTER TABLE rules.pr_data_dm_admmart_pred ALTER COLUMN pxInsName TYPE varchar(255);

For more information, see Adaptive Decision Manager data model.

Known issue: SAML IdP import uses only the last certificate

When you configure the identity provider for a SAML SSO authentication service, the backing keystore rule for the verification certificate is created with only the last certificate from the IdP metadata, instead of using all of the certificates. 

Search and Reporting does not index large items

When using the Search and Reporting (SRS) microservice in Pega Platform™ 8.5, you might encounter problems with indexing large out-of-the-box rules. The issue is not visible in Queue Processors, but you can access logs to verify which items the system does not index.

Tags disappear from Rich Text Editor source mode

When you use Rich Text Editor in HTML source mode, some tags disappear from the markup, which causes backward compatibility issues and data loss.

Cause

Pega Platform™ version 8.5.5 introduced the DOM Purifier security plugin. The plugin removes potentially vulnerable tags, including custom tags, from the raw HTML code in the Rich Text Editor source mode.

Workaround

You can disable the DOM Purifier plugin by adding the the window.disableDomPurifier = true markup to the userWorkForm HTML fragment rule.

Alternatively, as of Pega Platform version 8.5.6, you can add a tag to the allow list by including the window.rteCustomAllowedTags = ['myCustomTag'] snippet in the userWorkForm HTML fragment rule. 

In Pega Platform versions 8.5.6 to 8.6, the iframe tag is added to the allow list by default.
