NumberTextField and RangeTextField should always render/parse it's value with
English locale
--------------------------------------------------------------------------------------------
Key: WICKET-3591
URL: https://issues.apache.org/jira/browse/WICKET-3591
Project: Wicket
Issue Type: Bug
Components: wicket-core
Affects Versions: 1.5-RC3
Environment: client with a locale where the decimal mark is not a
period
Reporter: Attila Király
Wicket started adding some support for the new Html5 input types. Among these
are NumberTextField for number type [1] and RangeTextField for range type [2].
The Html5 spec mandates that the "value", "min", "max" attributes for these
inputs are floating point numbers. Html5 spec also describes the format of a
float number [3]. Simply to say it is a number formatted with English locale
(for example: decimal mark is a period).
Wicket currently renders min and max spec compliant but renders the value wrong
because it uses the client locale for that. Which means for example for a
Hungarian client it will generate "3,14" instaed "3.14". This breaks the custom
widgets used by browsers for these new inputs (Chrome and Opera have custom ui,
FF and IE stil use plain text field) because they except the value with a
period decimal mark. This means that browsers will post the value formatted in
English locale too so parsing is also broken for these on the wicket server
side because the client locale is used there also.
Imho wicket should always use the English locale for rendering/parsing these
values in case of these input types.
To reproduce you can use the form examples from "wicket-html5-examples" in the
wicketstuff project (I found this bug there).
