Is there a reason why the default composer email address field [Field-Email] doesnt allow capital letters as part of any of the local mailbox or domain name?
Apparently Hello@Example.com / email@example.com might be 2 different email addresses hence the case should be ignored when validating the value entered by a user. The current data validation actually prevents the user from entering a correct email with capital letters.
This is due to the regular expression we have chosen to use for Composer's email address fields. Domain names are case insensitive which is why the domain is lowercase only and the user name is reasonable to change to allow uppercase letters. This can be changed on the field by adding A-Z next to a-z in the existing regular expression and this can be set in a stylesheet so all fields on your forms get this setting.
thanks Glenn, that answers my question. We'll enhance the email field data validation in our project's composer datapacks (aliasing). I have raised an internal Avoka ticket to push the same into the Composer libs.
Why would you alias this and not just add a typed style in a stylesheet ?
