Highlighting Mandatory fields on UI

Hi All,

I have made a field mandatory through feeder class and implemented CHECK_ENTITY in usmd_rule_service to show error message for blank value.

Field is marked in asterisk(*),but the field is not highlighted in red on throwing error message.

I have tried using method of request_focus_on_field of io_extended_ctrl but even then field is not highlighted.

Please provide a solution on this.

Thank You!
