Error messages about hmda-platform-tools

[colleenms]

I suggest using more positive language in the error messages, similar to our approach for the beta release. Here is suggested wording for the current edits:

"Please enter a LEI/Loan ID combination in order to generate a check digit"

"Please enter a valid LEI/Loan ID combination that meets the following requirements:

• Legal Entity Identifier = alphanumeric and up to 20 characters in length
• Loan/Application ID = alphanumeric and up to 23 characters in length"
  (we could show the language only for the data element that is not meeting the specifications)

"Please enter a ULI that meets the following requirements:

• ULI is a combination of the LEI, Loan ID and check digit
• Legal Entity Identifier = alphanumeric and up to 20 characters in length
• Loan/Application ID = alphanumeric and up to 23 characters in length
• Check Digit = numeric and two characters in length"
  (we could show the language only for ULI and the data element that is not meeting the specifications)

In the platform, the user creates a password from scratch. If they didn't meet the password requirements, they have to go back and create another one, and that can be very frustrating. There's an up-front cost (in user attention) to listing the password requirements, but that cost is worth it to avoid the frustration of having to do it over again.

In the check digit tool, users aren't making up a LEI/Loan ID, they are more likely copying/pasting. So the up-front cost of initially listing the LEI/Loan ID requirements isn't offsetting much of a burden, and I think we should only show errors when they occur.
