Issue

When rule-based read-only conditions function incorrectly in embedded tables after updating to Pega Infinity^{TM ‘}25.

Symptoms and Impact

When rule-based conditions are not triggered as expected while user is interacting with the screen/embedded table. The UI does not render correctly when the condition is met.

Steps to reproduce

1. Configure a When rule-based read-only condition on a field in an embedded table based on another value in the row
2. Update the values in the embedded table that result in condition returning True
3. Verify if the field (mentioned in step 1) remains read-only

Root Cause

The calculation for When conditions takes place in the server. This introduces a delay and prevents the cell from being re-rendered once the results from the When conditions are received from the network call.

Solution

Update to Pega Platform 25.1.2.

As a workaround, use a custom condition instead of a When rule.

Or

Consult Pega Support for hotfix.
