DT condition expressions evaluate incorrect property on mobile



The When condition evaluates incorrectly in data transforms on a mobile device when nested in the Update Page blocks. This occurs in In iOS.

When running a property update offline on a mobile device, Console logs are generated indicating that the incorrect context is evaluated,

-Running data transform PegaSample_SetFirstName in pyWorkPage page context
-expression: translate: pega.process.expression.getValue(".FirstName","pyWorkPage.Person")=='Pega'

pyWorkPage.Person.FirstName is evaluated instead of pyWorkPage.Person.Name.FirstName with the Pega application.

This occurs when passing an embedded page as pageContext param to pega.offline.runDataTransform().

Error Messages

Not Applicable

Steps to Reproduce

Create a data transform containing a When condition in the Update Page block using an embedded property as part of the expression.

For example:

1. Update Page ".Person.Name" (embedded page on pyWorkPage)
1.1. When '.FirstName== "Pega"'
1.1.1. Set .Property = "Test".

Root Cause

A defect in Pegasystems’ code or rules.


Perform the following local-change:

Update the data transform rule such that .Person.Name is split in to two Update steps.
