To fix it I had to overwrite the validator

I tought that my formatter was doing enough, defined like so:
DecimalFormat formatPourcent = formatPourcent = new
DecimalFormat("0.0");
formatPourcent.setMinimumFractionDigits(2);
formatPourcent.setMultiplier(100);
formatPourcent.setMaximumFractionDigits(4);
I'm sure I miss something and doesn't need to overwrite
validatePourcentageEstime, how do you do ?
Ah ha! That formatter is NOT doing what you think it is:
From the JavaDocs:
Currently, the only classes that parse returns are Long and
Double, but callers should not rely on this.
It is returning a Double and KVC (or EOF?) is creating from that.
You either need to to set the scale in the validate method, or
create a BigDecimalFormat that does the right thing. So that
explains why you were getting the SQL error.
Is it changed in java 1.6 ? because in 1.5:
http://java.sun.com/j2se/1.5.0/docs/api/java/text/DecimalFormat.html#parse(java.lang.String,%20java.text.ParsePosition)
in the parse definition we have:
• If isParseBigDecimal() is true, values are returned as BigDecimal
objects. The values are the ones constructed by
BigDecimal.BigDecimal(String) for corresponding strings in locale-
independent format. The special cases negative and positive infinity
and NaN are returned as Double instances holding the values of the
corresponding Double constants.
I just Googled DecimalFormat, must have gotten an old version.
I'll first try to add:
formatPourcent.setParseBigDecimal(true);
and if it doesn't work, I'll keep the validate method.
Thanks again for the pointer !
