When creating/managing Tariff Plans, I occasionally get this error:
Invalid Data
Plan contains invalid data, fix errors before saving
What is really infuriating is that there are no indicators on the page as to which field is generating the error. I just spent 10 mins troubleshooting one instance only to find that the Name of the plan was too long. 10 mins of trial and error for something that simple.
It would be really appreciated if the error dialog could at least tell you which field was causing the error. Even better would be real-time data validation on each field so that if you enter something which is invalid, it will warn you immediately.
