hello, when you define a field in a table as a decimal(x,y) , the form
widget renders it as an <input class="decimal(x,y)" .../> .
I'm not perfectly sure that before worked right, because I noticed the
behaviour writing a letter accidentally inside a field, but I guess
before class for inputs of type decimal(x,y) would be simply rendered
as "decimal".
the current web2py_ajax checks for "decimal" as a class with the
following snippet
----
jQuery('input.double,input.decimal').keyup()
-----
and in this way pre-validation does not work.
