TimeZoneSelector... needs page refresh?

[mcohnen]

Hi,

I'm trying to use timeZoneSelector to change the timeZone. This is what I do:

--#{timeZoneSelector.timeZoneId}-- 
          <h:form>
               <h:selectOneMenu value="#{timeZoneSelector.timeZoneId}">
                   <f:selectItem itemLabel="Madrid" itemValue="Europe/Madrid"/>
                   <f:selectItem itemLabel="Dublin" itemValue="Europe/Dublin"/>
               </h:selectOneMenu>
               <h:commandButton action="#{timeZoneSelector.select}" value="Selecr"/>
          </h:form>
          <h:outputText value="#{test.date}">
               <s:convertDateTime type="time" /> 
          </h:outputText> - 
                    #{test.date}

I can see that the timeZone changes (Because of the first line where I print the timeZoneId) but the s:convertDateTime is not using the new selected TimeZone, unless I refresh the page! So clicking on the button launchs the form, changes the timezone, but s:convertDateTime is not aware until I refresh the page (f5).

What am I doing wrong? IS this a bug? Is there a way I can make this workd?

Thank you a lot!

I think the error is related to s:convertDateTime... and it also happens with f:convertDateTime! If i specify the timezone using a valueExpression, it looks like if it is being cached and not using the new value!

Any help here?

(Disclaimer: I have no idea if this is the reason, but it appears to be related to other problems I've had so this is worth a try :P)
My guess is that you need to rebuild your page after selecting a timezone. If your action=#{timeZoneSelector.select} returns null/void then you are using the exact same component tree that you started with. It will not be rebuilt (I use " because there's a more technical way to describe this :P).

Try making your action method return a value so that your page is rebuilt.

Null/Void methods use the same UIViewRoot, non null/void returns from action methods cause a new UIViewRoot to be created. I hope this helps.

As in timeZoneSelector.select should return timezoneSelection.xhtml or whatever your page is.

Hi, thank you very much for your answer. You are right, it is using the same component tree until I reload the site. But how can I force a new UIViewRoot to be created? I tried what you said, returning the xhtml, but it's not working...

Howevery I found that Trinidad (Apache Myfaces) converter for dateTime works as expected. It is a shame I have to add the jars only for this purpouse...

Let's see if I can get rid off a whole framework (Trinidad) that I'm using for a tag! Hehe

Thank you!
