Roger Whitcomb updated PIVOT-892:
---------------------------------
Attachment: 892.patch
The "892.patch" file is what I've come up with to resolve this issue.
Basically the only way to instantiate a NumberFormat object to recognize
scientific notation is to use a pattern. This code appears to work correctly
in all my tests to recognize general decimal and scientific notation for input.
> DoubleValidator and FloatValidator do not allow exponents to be entered

> 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".
