Field not displayed correctly in Web Mashup



Web Mashup embedded in an external IAD application fails to populate a label based on a dropdown list on selection.
Pega application does not have Web Mashup and is accessed through Oracle OCX application from a SnapStart URL.

Error Messages

Error: You lack access required to execute Rule-Obj-Activity.pxCallObjOpen   [Tracer]
[http-apr-8080-exec-6] [1529562507] [ ] [] (internal.mgmt.Executable) ERROR Host details  | Username - Execution denied for class: CLASS NAME (activity: pxCallObjOpen)

Steps to Reproduce

  1. Run the use case.
  2. Select a value from the dropdown in IAD. The label is not populated based on the selection.

Root Cause

A defect or configuration issue in the operating environment.
The custom class was unable to execute the pxCallObjOpen. Therefore, the data transform failed to retrieve the required details from a data page.


  1. Create an access role in the user's access group
  2. Add the affected class and grant full permissions (5) to it to execute reports and activities.
