Steps to Reproduce



Not Applicable


Root Cause



A software use or operation error.
pzRemoveDataPage is invoked during the Refresh Current Harness with the parameter as D_CaseStageCount' to remove the data page from the Clipboard. This activity uses the Param.DataPage as a Step page. Hence, the data page (Load activity) is reloaded without a class name.


Resolution



Perform the following local-change:

Use pyRemoveDataPage instead of the pzRemoveDataPage out-of-the-box activity.
