INC-141579 · Issue 591852

Enhancement added for node heartbeat recovery process

Resolved in Pega Version 8.3.5

Nodes were not showing up in the admin portal even though they were up and running and could be seen in the pr_sys_statusnodes table. The exception "An exception was encountered while invoking the cluster membership listener callback" was seen. All nodes became visible again after multiple restarts. The root cause was traced back to a temporary database connectivity problem. The database itself was fine according to database monitoring reports, but a network problem, a slow database query, or another issue prevented Pega from establishing a connection for more than a minute. An enhancement has been made to resolve this: if a node becomes unhealthy due to the service registry missing due to a failed heartbeat, the heartbeat will try to recover after 60 seconds and keep trying every 30 seconds until it succeeds.

Resolved Cassandra query read/write latency

Resolved in Pega Version 8.3.5

Read/write latency was seen when certain Cassandra queries were triggered by the system. This was traced to an unusual case where a flush was not done for an exceptionally long time period, and has been resolved.

Fixed flow line distortion in Process Modeler

Resolved in Pega Version 7.1.9

When clicking through to a subprocess from a parent flow (by clicking the + sign in the blue subprocess shape), flow lines in the subprocess were shown in a distorted fashion. When opening the same flow in a separate tab (by right clicking the blue subprocess shape and selecting Open Flow) the flow lines were correctly painted. This was an issue caused by the different renderings of the flow depending on whether there was a click through to it (with the + on the parent flow?s subprocess shape), or the subflow was opened in a separate tab (with open Flow). After the Process Modeler saved and checked-in the flow, the connector lines were re-drawn in ways that were non-intuitive and hard to interpret due to the edge routing in PM being calculated off incorrect input data that was taking into account shapes that were not represented on the screen. To fix this, the system now ensures the edges are routed without taking into account any shapes not represented on the canvas.

Fixed scrumboard intermittent failure

Resolved in Pega Version 7.1.9

After upgrading, it was seen that the scrumboard would intermittently fail to load, partially displaying and then hanging if the columns did not fit within the window boundaries due to the number of elements. This was traced to an error in the functionality that resizes parts of the scrumboard, and has been fixed.

Number formatting made consistent for Propositions

Resolved in Pega Version 7.2.1

In Proposition landing, a decimal property was rounded to three digits when shown in read-only mode but clicking on the edit option for the Proposition displayed the entire number with all the digits after the decimal. This was not a desired difference, and the presentation setting for Double type property has been modified to show all numbers after the decimal.

Predictive Analytics rulesets excluded from RSA

Resolved in Pega Version 7.2.1

The Pega-provided Predictive Analytics rulesets were being incorrectly being checked and flagged by the Rule Security Analyzer. The PAD rulesets have now been properly excluded from the RSA check, and further analysis was done to find and fix other RSA flags that should have been excluded.

SR-A18333 · Issue 237135

Corrected JSON page group handling

Resolved in Pega Version 7.2.1

If DataSet-Execute method was used to cache a CustomerPage from Clipboard, using the same DataSet-Execute method to retrieve it from the cache using the "Browse by key" operation was not working correctly: If the page contained a page group property, then the retrieved CustomerPage contained additional invalid entries that led to errors in the mapping logic. This was an issue with the Clipboard page JSON converter not properly handling page groups, and has been corrected.
