I have a use case where a form field has to be validated by a REST Call, and if the validation fails the user needs to be alerted and prompted to try again. Currently, the form is initially filled as part of the process initiation, so if the validation fails it just creates a new task under 'Tasks' and the user often doesn't realise. Is there a way to flash an alert telling the user to go check 'Tasks' or that the validation failed?
