But I'm puzzled why Stephen's original approach doesn't work.
>From a brief look at the code, the f:convertNumber will attach a
NumberConverter instance to the object that is used to map
number->string.
The NumberConverter simply uses the javax.text.NumberFormat class for
conversions. The sun javadocs are fairly vague, but I would have thought
that
NumberFormat.setMaximumFractionDigits
(which is what the converter is calling in this case) would do what
Stephen already wants, or at least have some effect on the output!
Stephen, you might like to try writing a trivial test app to see how the
javax.text.NumberFormat.setMaximumFractionDigits method actually affects
later calls to
NumberFormat.format(new Double(6.977777));
BTW, you might need to specify a "rounding mode" for the NumberFormat to
get the output you want (6.97 --> 7)
