Sebastian commented on WW-2349:
-------------------------------
Ok maybe I have found the cause of this issue. Some developer disabled the
localization for Number to String conversion in
com.opensymphony.xwork2.util.XWorkBasicConverter, line 76:
<snip>
if (toType == String.class) {
/* the code below has been disabled as it causes sideffects in
Strtus2 (XW-512)
// if input (value) is a number then use special conversion method
(XW-490)
Class inputType = value.getClass();
if (Number.class.isAssignableFrom(inputType)) {
result = doConvertFromNumberToString(context, value, inputType);
if (result != null) {
return result;
}
}*/
// okay use default string conversion
result = doConvertToString(context, value);
</snip>
Well, it seems that disabling this code also has serious side effects, as it
causes the mentioned problem when using a non-English locale.

> Project: Struts 2
> Issue Type: Bug
> Components: Core Actions
> Affects Versions: 2.0.11
> Reporter: Sebastian
>
> Locale is set to de_DE.
> Action contains a property
> private Double percentage;
> with getters/setters. The corresponding page contains a "textfield" tag for
> this property. It only accepts a "," (comma) as a decimal separator due to
> the set locale. This is fine and ok.
> But when I preset the Double property to a certain value and render the page
> afterwards, the textfield is filled with a number using the "." (dot) as
> decimal separator, instead of comma.
