INC-142569 · Issue 597897

CORS headers added for Health check URL

Resolved in Pega Version 8.4.4

Pega Health Check URLs were throwing CORS error when invoked for application Health checks. This has been resolved by adding CORS headers for pingService responses.

INC-142831 · Issue 605476

Corrected Outlook web inline image handling

Resolved in Pega Version 8.4.4

Outlook web was not able to render inline images and instead added them as external attachments. Investigation showed inline images were not being rendered properly in Outlook web due to the disposition not being set. This has been corrected.

INC-143195 · Issue 596846

BLOB utility modified for better memory usage

Resolved in Pega Version 8.4.4

An out of memory error was encountered when running the utility for handling corrupted BLOBs. This has been resolved by modifying the utility to get the rows in batches.

INC-143376 · Issue 604531

Adding handling for property without parent page

Resolved in Pega Version 8.4.4

Filtering was not working for a DateTime control in an optimized grid with embedded property which was a function alias defined in a report definition referenced by a Data Page. This was traced to the system assuming that every property has a parent page, which this use case did not. To resolve this, an update has been made that will return null for the parentGroupOrListProp if one does not exist.

INC-143461 · Issue 601842

Updated JSON DT nested page property handling

Resolved in Pega Version 8.4.4

In a JSON data transform, when using an "Update page" step on a single-page property, as a child step of an "Append and map to" step where a pagelist property is given, the pagelist was populated with only one result but the single-page property was treated like a pagelist and received multiple results. This has been resolved by updating the ClipboardJSONDeserializer implementation and downstream abstractions to support "clipboard only" relations as properties in nested PageLists.

INC-143865 · Issue 602198

Handling added for empty back link in BLOB

Resolved in Pega Version 8.4.4

A DirectStreamContainerV7 Exception (BLOB Corruption) was seen when opening a work object that expanded a certain property. This was traced to an empty back link present in the BLOB: during deserialization, the exception was thrown while trying to parse that empty back link. To resolved this, an update has been made which will parse the empty back link information properly.

INC-143908 · Issue 606551

Data Page Save correct in batch mode

Resolved in Pega Version 8.4.4

After configuring a List type savable Data Page with save activity in Code-Pega-List, the save data page was triggered from utility of flow from the queue processor to handle queueing 10k data items and creating 10k work objects. When this was run, a field dpClassName was being changed by different threads in DataPageSaverImpl.java. This has been resolved by making the class DataPageSaverImpl.java stateless to ensure thread safety.

INC-143972 · Issue 600522

Added handling to avoid class cast exception

Resolved in Pega Version 8.4.4

The error "doMaintain errorjava.lang.ClassCastException: java.util.HashMap cannot be cast to com.pega.pegarules.priv.factory.SequencedEntry" appeared in production numerous times per day, leading to exceptions. Investigation showed this was being triggered from the activity Show-harness, and was traced to the ConcurrentMostRecentlyUsedMap eviction method casting entries to Sequenced entries. There is no such check while putting entries. To resolve this, a wrapper has been added over the ConcurrentMostRecentlyUsedMap object to avoid a class cast exception.

INC-144387 · Issue 605342

Support added for allow list for LaxRedirectStrategy

Resolved in Pega Version 8.4.4

When using Connect REST with POST to access a third-party service deployed on multiple nodes, the load balancer sometimes replied 302 with Location header. The ability to allow the REST connector to automatically follow these redirects even in the case of POST messages is supported by Apache http client via LaxRedirectStrategy, but REST Connectors need both rule and engine enhancements to allow for this. To support this use, an allow list has been implemted for hostnames. This will allow the connector to be configured to follow the LaxRedirectStrategy only when the hostname of the redirect location is in the allow list. The default will continue to block the redirect.

INC-144601 · Issue 602425

Empty addresses removed from email

Resolved in Pega Version 8.4.4

After upgrade, an issue was seen when sending email to multiple 'To' addresses generated an exception if any 'To' address had an empty value. To resolve this, a check has been added that will remove any empty address from the recipientTo address list.
