how to get calender fire backing bean action method?

[gothmog]

Hi,

Can someone tell me how to get an action method firing when the user clicks a date. Nothing I've tried seems to work.

<a4j:form>
 <a4j:outputPanel>
 <rich:calendar id="date" popup="false"
 currentDateChangeListener="#{testPage.changeDateListener}"
 valueChangeListener="#{testPage.changeDateValue}"
 value="#{testPage.currentDate}" />

 </rich:calendar>
 </a4j:outputPanel>
</a4j:form>

Backing bean

private Date currentDate = null;

public Date getCurrentDate() {
 return currentDate;
}

public void setCurrentDate(Date currentDate) {
 this.currentDate = currentDate;
}

public void changeDateListener(CurrentDateChangeEvent event){
 log.info("changeDateListener()value=" + event.getCurrentDateString());
}

public void changeDateValue(ValueChangeEvent event){
 log.info("changeDateValue()old=" + event.getOldValue() + ";new=" + event.getNewValue());
}

None of the backing bean events fire when you use the mouse to change the date.

What am I missing ?

Try using a4j:support

<a4j:support event="ondateselected" action="#{bean.someAction}"/>
<a4j:support event="oninputchange" action="#{bean.someAction}"/>

Thank you !! it works :) - I had to upgrade to 3.1.1 from 3.1.0

B.t.w 3.1.2 is already released. ;) And in the middle of november we plan to release 3.1.3 version ;)

Excuse me,

but in the example above to code work (ie, to fire backing bean action method) do we have to specify both valueChangeListener and currentDateChangeListener?

currentDateChangeListener="#{testPage.changeDateListener}"
valueChangeListener="#{testPage.changeDateValue}"

and do we need to specify Ajax support for both types of events:

<a4j:support event="ondateselected" action="#{bean.someAction}"/>
<a4j:support event="oninputchange" action="#{bean.someAction}"/> ?

I'm a newbie so please forgive also my next question:
I believe that event="oninputchange" corresponds to valueChangeListener,
but does event="ondateselected" corresponds to currentDateChangeListener ? if so then it is not called "ondatechange" ?

Thank you

Hello,

"ondateselected" handler should be enough for just clicking the date; "oninputchange" handles manual input changes if it is allowed by calendar.

"ondateselected" corresponds to valueChangeListener, but may additionally trigger CurrentDateChangeEvent as well if the date from another month was selected.
