Discussion: Develop & implement an approach to error handling. #17

Currently, the HTML5 application does not notify the user when an error results from a failed request. The application also does not update the UI in anyway in the event a request for Data fails. It might not be appropriate to notify the user in all cases but we should discuss these scenarios to give the best user experience possible.

This would be a good question for the community. What approach should be taken?

It is not appropriate to notify in all case. Depending on lots of things:

Mobile Browser Context...
Client / Back Side SPOF
XMLHTTPrequest 1 - 2 error handling
Cas / Shibb / Other (openssl)
switching WIFI to EDGE
encoding
App Cache... ...

This issue has been handled with recent commits to master. Error handling has been implemented in the following cases:

On the login form. Login validation with error messages have been added.
In the event that a user attempts to login into umobile and something goes wrong with the ajax request to obtain a user's layout (json) information, we keep the user on the login form and display an error message prompting the user to try to login again. The previous implementation left the UI in a broken state.
