Matthias Weßendorf commented on TRINIDAD-1124:
----------------------------------------------
I now noticed that there is a setParseBigDecimal( bool ) on DecimalFormat
(which is used).
Setting this to true is the fix. It may be a little bit expensive, but at the
end, we are safe with this fix
> numberconverter has issue with bigdecimal

> URL: https://issues.apache.org/jira/browse/TRINIDAD-1124
> Project: MyFaces Trinidad
> Issue Type: Bug
> Reporter: Matthias Weßendorf
> Assignee: Matthias Weßendorf
>
> Due to a potential bug in BigDecimal there is a bug, when you use BigDecimal
> with a NumberConverter.
> Like
> <tr:inputText value="#{bean.number}" ...>
> <tr:convertNumber />
> </tr:inputText>
> For instance, when the entered value is "333.111" the actual stored value is
> 333.1109999999999899955582804977893829345703125
> There is a mathematic explanation for that in here:
