Issue with Data Transform used in connectors in flow



 Parameters are not getting propagated from Data transform to other activities or data transform, used in subsequent shapes of the flow When defined Data transform in Connector of a flow.

Error Messages

No error message.

Steps to Reproduce

  1. Create a flow.
  2. In the connector call a data transform and set few parameters.
  3. In the next shape call a data transform and refer the parameters.
  4. Observe that parameter values are not passed.

Root Cause

An issue in the custom application code or rules.


There is no option from the UI to pass current parameter Page from a flow.
Hence, in the context of the Data transform, a new parameter page is created and the parameter page values that are set here are not sent back to the flow.

Supporting this requires major changes like changes in generated java as well as UI changes providing a checkbox to pass current parameter page.
So, Pega SME's confirmed that  this would be treated as an enhancement request and pursued in the next release.

Following are the local-change steps:

1.Use Set properties to set Param Page values instead of a data transform.
2. Use properties on the primary page in the data transform and set values on them. Later, these properties can be used in the utility activity.
