------------------------------------------------------------------------------------------------------------------------------

                 Key: WW-1917
                 URL: https://issues.apache.org/struts/browse/WW-1917
             Project: Struts 2
          Issue Type: Bug
         Environment: Linux, JDK 1.6.0, Tomcat 5.5.17, Struts 2.0.6, Eclipse 3.2 Callisto,
Firefox 1.5
            Reporter: Torsten Römer
         Assigned To: Musachy Barroso


- Deploy struts2-blank-2.0.6
- Create /example/Datepicker.jsp:

<%@ taglib prefix="s" uri="/struts-tags" %>

<s:head theme="ajax"/>

<s:form action="Datepicker">
	<s:datetimepicker label="datepicker" name="datepicker"/>
	<s:submit/>
</s:form>

Locale: <s:text name="%{locale}"/>

- Create example.Datepicker.java:

package example;

import java.util.Date;

public class Datepicker extends ExampleSupport {

  private Date datepicker;
  
  public String execute() throws Exception {
    return SUCCESS;
  }

  public Date getDatepicker() {
    return datepicker;
  }

  public void setDatepicker(Date datepicker) {
    this.datepicker = datepicker;
  }
}

- Add action Datepicker to example.xml:

        <action name="Datepicker" class="example.Datepicker">
            <result name="input">/example/Datepicker.jsp</result>
            <result name="success">/example/Datepicker.jsp</result>
        </action>

- Rebuild/restart the example app
- (Linux) Open a console and check/set the LANG variable. Example: LANG=de_DE.UTF-8
- Start Firefox from the console
- Go to the URL http://localhost:8080/struts2-blank-2.0.6/example/Datepicker.jsp
- Pick some date, the format is dd.MM.yy (this is the correct format for German locale) 
- Submit the form: No error
- Add request_locale=en_US to the URL: http://localhost:8080/struts2-blank-2.0.6/example/Datepicker.action?request_locale=en_US
- Pick some date, the format is still dd.MM.yy (while I think it should be US locale now)
- Submit the form: There is an error: Invalid field value for field "datepicker", and the
redisplayed date is NaN.NaN.aN

- When changing the request_locale back to de_DE, there are no more errors

- When adding the attribute displayFormat="yyyy-MM-dd" to the tag, the form subission always
fails with the above error, even if request_locale=de_DE
