We have a group doing the SAE course at our company and more than one person has hit the same error when creating the Onboarding case. There seems to be no issue when doing the verification run through of the case during the end of UI module but once running it after the Data Pages exercise, the error occurs. While running the Onboarding Case,the Create Employee initial section does not display the embedded section from the data Employee class and when submit is clicked the following error appears: (see attachment)
You can set it in the pySetFieldsDefaults data transform in the in TGB-HRApps-Work-Onboarding class. When the Onboarding case is instantiated it will reference the pyDefault data transform which in turn will reference the pySetFieldDefaults. In the pySetFieldsDefaults just add a row and set the target as .Employee.pxObjClass and the source as TGB-HRApps-Data-Employee.
