The feature for required fields definitely meets the basic requirements, but I think it would be great to be able to customize the appearance of the popup you see when one of your required fields isn't populated.

I also find the wording a little awkward for non-programmers.
"Parameter [form field] is required"

Changing the wording isn't too difficult; I found where that is in the code. However, it would be great if we could use the bootstrap modal dialog for these type of alerts too. That would look much more polished.

FYI - I accidentally assigned this to Problems. I tried editing the post and changing it to Ideas, but it won't save it to anywhere else other than the Problems section....

Hello,
Unfortunately you cannot style the default alerts that appear. You can turn them off and use behaviors in order to show some custom alerts(using the responsive notify extension for example), but the event is the same for all types of error "When an error has occurred".

Would client-side validation work with the new database connector extension when inserting or editing database records? Take your own Universal Form Validator extension for example... could I use that with my inserts and edits created with database connector?

Hello,
The validation option for HTML5 Data Bindings is still work in progress, when it is ready it will include database checks for insert/update records.
