DT runs differently on offline mobile application and desktop

SA-43678

Summary



Data transforms evaluate differently on a desktop browser when compared to an offline mobile application. Specifically, an 'undefined' property evaluates as equal to string '0', when evaluated offline.


Error Messages



Not Applicable


Steps to Reproduce

  1. Set up a data transform to execute on the load of a flow action.
  2. Set up a condition in the data transform: if .MyProp == "0" then set TargetProp to "Hello World".
  3. Test this use case on a desktop browser and on a custom mobile application.


Root Cause



A defect in Pegasystems’ code or rules. Expressions were evaluated incorrectly in the translateExpression function of pzpega_process_expression.js.


Resolution



Apply HFix-37068.
