Datatable + date problem

[ronanf]

Hi,

I have a problem where the richfaces datatable displaying a date does not appear to display the correct date (it is out by one day).

The long (date) in the basic sample i've created below is a date I have stored in a database.

Test Bean:

public class TestBean {
     private List<Date> dateList;

     public TestBean() {
          dateList = new ArrayList<Date>();
     
          Date d = new Date();
          d.setTime(1274742000000L);

          SimpleDateFormat sdf = new SimpleDateFormat("d-MMM-yyyy");
          System.out.println(sdf.format(d));
          dateList.add(d);
     }

     public List<Date> getDateList() {
          return dateList;
     }
     
     public void setDateList(List<Date> dateList) {
          this.dateList = dateList;
     }
}

Test JSF:

<rich:dataTable id="docListDataTable" value="#{TestBean.dateList}" var="date" width="100%" columns="1" columnsWidth="100%">
     <rich:column id="c4" title="Date">
          <f:facet name="header">
               <h:outputText id="h4" value="Date"/>
          </f:facet>
          <h:outputText id="o4" value="#{date}"/>
     </rich:column>
</rich:dataTable>

The output of the above will be a table like this:

Date

24-May-2010

However the same date which is displayed in the table as 24-May-2010 is outputted to the console as 25-May-2010. You can also perform a .toString() on the date object in the example and it too will print the 25-May-2010.

This inconsistency has caused me a lot of problems because the last place a looked was the rendering of the date object. Am I doing something wrong or is this a bug?

Thanks,

Ronan

I should note this has been tested and occurs in 3.3.3 FINAL and 3.3.2 SR1.

Hi Nick,

Do you believe this is a time-zone issue? My server resides inside the default GMT time-zone so I had discounted that idea. I tried the following but the same problem occurs:

<h:outputText id="o4" value="#{date}">
     <f:convertDateTime timeZone="GMT"/>
</h:outputText>

The alternative is to write a custom converter?

Before writing custom converter, I'd suggest to check what's wrong with the standard one. It should output date properly.

Thanks for your input. It looks like it was a timezone problem and I had to link the above into a backing bean like so:

public TimeZone getTimezone() {
     return TimeZone.getDefault();
}
