--------------------------------------
Hi Roger, now it's much better :-) ... but still it need some fix, sorry ...
some info, with my other tests with TestInputValidatorTest:
double validator: up to this 9e3000000000000000000 gives valid, but isn't too
much for doubles ?
(and the same even for 9e-3000000000000000000 )
I still have problems with float numbers, because for example we put the
initial value for the float value to "0.5" but in my Locale (Italian) the right
string value is "0,5" ... so at least we should use the Locale to write/read
those string values (and write in comments at right) ... for me it would be
simpler to do (because I can immediately see it), ok ?.
Probably a good addition to that test application could be to write in
System.out the input value, and the calculated value, just to be sure and check
by hand.
I hope to find some time to help you on this (if you want) ... tell me (I can't
commit but I can attach here a patch).

> Project: Pivot
> Issue Type: Bug
> Components: wtk
> Affects Versions: 2.0.2
> Environment: All
> Reporter: Roger Whitcomb
> Assignee: Roger Whitcomb
> Priority: Minor
> Labels: validation
> Fix For: 2.0.3

> Attachments: 892.patch, num.patch

> Original Estimate: 1h
> Remaining Estimate: 1h
>
> The DoubleValidator and FloatValidator classes rely on a default NumberFormat
> instance to do parsing, however, a DecimalFormat is necessary in order to
> recognize floating values entered with exponents.
> As a result, using one of these validators currently will fail to validate a
> valid floating-point number such as "3.0e20".
