Leonardo Uribe commented on MYFACES-3195:
-----------------------------------------
Could you provide an example when groupingUsed should be used when parsing?
Obviously the previous example is expected, but it is necessary to find another
example where this could be a problem to fix it.
> NumberConverter ignores groupingUsed attribute when parsing

> Key: MYFACES-3195
> URL: https://issues.apache.org/jira/browse/MYFACES-3195
> Project: MyFaces Core
> Issue Type: Bug
> Components: General
> Affects Versions: 2.0.7
> Environment: Linux, Tomcat, Spring, Hibernate, ... (please ask for
> more details)
> Reporter: Bastian Voigt
> Assignee: Leonardo Uribe
>
> javax.faces.convert.NumberConverter uses the "groupingUsed" attribute only
> for formatting, but not for parsing numbers. This leads to a nasty bug:
> When I input the value "0.23" in an input field using a German locale, it is
> converted to "23.00", which is bad.
> Proposed patch, in method getAsObject():
> NumberFormat format = getNumberFormat(facesContext);
> format.setParseIntegerOnly(_integerOnly);
> + format.setGroupingUsed(_groupingUsed);
