Jesse Kuhnert resolved TAPESTRY-137:
------------------------------------
Fix Version: 4.0.1
Resolution: Fixed
Assign To: (was: Tapestry Developer List)
> NumberValidator's error messages are localized, but parsing/formatting is not
> -----------------------------------------------------------------------------
>
> Key: TAPESTRY-137
> URL: http://issues.apache.org/jira/browse/TAPESTRY-137
> Project: Tapestry
> Type: Bug
> Components: Framework
> Versions: 3.0
> Environment: Operating System: Windows XP
> Platform: PC
> Reporter: Davide Orlandi
> Fix For: 4.0.1
>
> Error messages from NumberValidator are formatted using locale settings
> (since
> they are built from MessageFormat.format()) but parsing and formatting is not.
> So, for example, if the minimum value constraint is set to 12345, an user
> typing "5000" in a ValidField would get this error:
> "test numeric field must not be smaller than 12,345."
> And typing "12,345" (pasting exactly from the error message) he would get:
> "test numeric field must be a numeric value."
> This can be quite misleading for users, especially in non-english locales: an
> italian ResourceBundle of ValidationStrings would display 12345 as "12.345"
> (yes, with the dot -- stupid locale rules :( ).
> Solutions: NumberValidator should format/parse using a localized NumberFormat
> (not so easy) or (easier) minimum and maximum should be toString()ed before
> passing them to formatString().
> Tested code (using Tapestry 3.0 beta 4 and Tomcat 5.0.18):
> --- Home.page ---
> <page-specification class="org.apache.tapestry.html.BasePage">
> <property-specification name="numericValue" type="java.lang.Integer" />
> <bean name="validator" class="org.apache.tapestry.valid.NumberValidator">
> <set-property name="minimum" expression="12345" />
> </bean>
> <bean name="delegate"
> class="org.apache.tapestry.valid.ValidationDelegate" />
> </page-specification>
> --- Home.html ---
> <html><body>
> <div jwcid="@Delegator" delegate="ognl:beans.delegate.firstError" />
> <form jwcid="@Form" delegate="ognl:beans.delegate">
> <input jwcid="@ValidField" validator="ognl:beans.validator"
> displayName="test numeric field" value="ognl:numericValue" />
> <input jwcid="@Submit" />
> </form>
> </body></html>
