Yogesh, I saw you set the Doc Text on this bug, but then removed it. Was that intentional? If so, why? I am hoping to add this as a Known Issue to the Release Notes. Updating the QA Contact to a Hemant. Hemant will be rerouting them to the appropriate QE Associate. Regards, Giri Updating the QA Contact to a Hemant. Hemant will be rerouting them to the appropriate QE Associate. Regards, Giri |
