Many times a field has an issue with either default or computed field code and we get a Form 500 or some other general error. Just having the error inform as to where the error is in the code such as the field name or the details on what caused the error. Today we can only see the error information by opening the form in notes and it will warn us about the field where the error resides. That becomes difficult for those forms meant for web only viewing/use. By default those will have many problems and issues rendering in the notes client.
