Re: Struts2 : formatting and entering doubles consistently through the whole application not depending on locale
reading the docs I discovered the possibility to override default typeconverters (cf: http://struts.apache.org/2.3.4/xwork-core/apidocs/com/opensymphony/xwork2/conversion/impl/XWorkBasicConverter.html ) == Quote from the docs As from version 2.3.2 you can override default converters by implementting TypeConverter interface and specifying beans in struts.xml as follow: I tried with that approach by creating a new TypeConverter (roughly copied from com.opensymphony.xwork2.conversion.impl.NumberConverter) adding the following line in struts.xml right after the tag but the webapp failed to start with the following error. Caused by: Bean type interface com.opensymphony.xwork2.conversion.TypeConverter with the name number has already been loaded by [unknown location] - bean - file:/D:/dev/tomcat/webapps/blank/WEB-INF/classes/struts.xml:10:132 at com.opensymphony.xwork2.config.providers.XmlConfigurationProvider.register(XmlConfigurationProvider.java:227) Am I missing something ?

Re: Struts2 : formatting and entering doubles consistently through the whole application not depending on locale
Locale.FRENCH and Locale FRANCE should output something like 345 987,246 i can confirm that with a slightly modified struts-blank app (defaultStack and a textfield mapped to a Double) i'm having a conversion error for Doubles too. It doesn't like the thousand separator (space) and it converts coma to point ( ',' to '.' ) Pierre. On Tue, Jun 19, 2012 at 9:33 AM, J.

Re: Struts2 : formatting and entering doubles consistently through the whole application not depending on locale
that's it, the parser expects localized input. I'd like to be able to handle parsing by myself for Doubles (without depending on the locale). I was able to register an application-wide DoubleConverter with primitive type double this way : == xwork-conversion.properties == # syntax: = double = com.company.app.DoubleConverter it works but it looks more like a hack than something i can rely on as it based on the bug Łukasz indicated (https://issues.apache.org/jira/browse/WW-3171). I might be surprised to see this no more working when this bug is fixed. Pierre.

Struts2 : formatting and entering doubles consistently through the whole application not depending on locale
In a localized application with 2 languages : French and English.
I want users to be able to enter (HTML ) doubles formatted the
same way wether they are using english or french locale.
i.e :
- english_user enter "445,000.00" for orderItem.price and this data is
correctly parsed to 445000.0d and put into the corresponding bean
property
- french_user enter "445,000.00" for orderItem.price and this is also
correctly parsed to 445000.0d and put into the corresponding bean
property
i'm using struts2 2.3.4 with defaultStack and jdk 1.5.0_22
i'm using s:textfield like suggested in the docs :
http://struts.apache.org/2.3.4/docs/formatting-dates-and-numbers.html
with english locale it's ok, with french locale it's not.
when submitting the form with french locale i have errors : "Invalid
field value for field xxx"
and in the logs i get : [WARN ]
com.opensymphony.xwork2.ognl.OgnlValueStack - Error setting
expression 'orderItem.price' with value '[Ljava.lang.String;@c98901'
(struts is trying to use a setter with a String parameter whereas it
should find the one with a Double parameter)
I've also tried using a Converter with no success (see code at the end)
Is there any (simple) way to achieve what i've explained here ?
Regards,
Pierre.
== Converter Code ==
public class DoubleConverter extends StrutsTypeConverter {
private static ThreadLocal decimalFormat = new
ThreadLocal() {
protected DecimalFormat initialValue() {
final DecimalFormat df = (DecimalFormat)
DecimalFormat.getInstance(Locale.US);
df.applyPattern("#,##0.00");
return df;
};
};
public Object convertFromString(Map context, String[] values, Class toClass) {
String myString = values[0];
if (myString == null || "".equals(myString)) {
return 0d;
}
try {
return decimalFormat.get().parse(myString);
} catch (ParseException e) {
throw new TypeConversionException(e);
}
}
public String convertToString(Map context, Object o) {
if (o == null) {
return "0.00";
}
return decimalFormat.get().format(((Double) o).doubleValue());
}
}
