I've been working on a T5 and Flash based website - building a version of
the good old acrophobia game. You can check it out at www.acrobabble.com. T5
is shaping up to be a great framework. However, I do have some feedback on
the form validation mechanism. As you can see from the acrobabble website,
if you just tab through the login fields, you get broken error messages
because of the div being too small where the blurbs are created. The
framework will never be able to properly guess where the blurb should be
inserted and as a consequence wrapped blurbs like I'm getting are
inevitable.
I really wish T5 would support validation like is seen on Yahoo mail's sign
up page. Go to yahoo.com and click on Sign Up for mail. The fields seem to
have various "tags" associated with them:
- Displayed when the field gets the focus
- Displayed when the field loses focus and validation occurs.
I saw a few emails that referred to validation using onBlur. I think every
field should be able to drive certain events:
onFocus: This should allow you to specify one or more components (say by
Annotation in the getter for the field) that should either have their css
changed or be ajax-updated when the field gets focus.
onBlur: Fire validations and allow the developer to specify in which html
tag (div or span, etc.) the output of the validation should be displayed and
optionally additional components that could have their css class changed.
This will make for an extremely powerful and flexible validation framework
and will get us away from the blurbs (which can be very annoying to use as
they cover up the field). My humble opinion is that the above change is a
necessity given the other superlatives that T5 boasts (hint: Howard - appeal
to ego! :)
