The default error handling for Sintel will render a message such as :
With my user base this is generally ignored.
My feature requests are:
- Make the error requests (optionally) modal.
- Allow errors to be mapped to custom titles and descriptions. For example make the error message above say: Your attachments did not upload. Please click on the Save button again to try again.
- Have error logging to either SharePoint or an alternate data source (obviously if the error is with the data connection that would make this difficult)
