A Mashup is called to Call an Harness and saved to a Data Table by calling an activity.
Data is getting saved into the table accordingly where email is primary key.However if user enter "Email" which already exists it needs to display message in the Harness. Using a Property-set-message the message is displayed in the harness when running standalone. However when running in Mashup validation message in pages are not getting displayed. Also when tried to call Load-Harness and tried to reload another its not loading in Mashup.
Can you please help out if any one resolved the issue.
