I'm making a webapp in Seam but ran into a problem I can't seem to fix.
I have a JSF form where the customer can select a
reservation type through a combobox. Based on the selected value, other form components gets rendered.
For example: the customer selects Hours as
reservation type, a panelGroup gets rendered where the customer can select a start- and an end hour. But if the customer would select 'part of the day' as
reservation type, a selectOneMenu gets rendered where the customer can select a part of the day (morning, afternoon, evening)
The rerendering well but the values of the components with a rendered conditional won't get passed to the bean. They stay null values.
This is the code i'm talking about:
<h:panelGrid columns="2">
<h:outputText value="
Reservation Type" />
<h:selectOneMenu value="#{selectedPeriodPart}">
<s:selectItems
value="#{productManager.getAvailableDayPartsSpot()}"
var="daypart" label="#{daypart.label}"></s:selectItems>
<s:convertEnum />
<a4j:support ajaxSingle="true" event="onchange" action="#"
reRender="spot"></a4j:support>
</h:selectOneMenu>
<h:outputText id="date_spot" value="Date" />
<a4j:outputPanel id="calendar_spot" layout="block">
<rich:calendar value="#{reservation.reservationPeriod.startDate}"
locale="en" cellWidth="24px" cellHeight="22px"
style="width:200px" />
</a4j:outputPanel>
<h:outputText rendered="#{selectedPeriodPart eq 'DAY_PART'}"
value="Daypart" />
<h:selectOneMenu value="#{selectedDaypart}"
rendered="#{selectedPeriodPart eq 'DAY_PART'}">
<f:selectItem id="si_morning" itemLabel="Morning (6:00 - 12:00)"
itemValue="morning" />
<f:selectItem id="si_afternoon"
itemLabel="Afternoon (12:00 - 18:00)" itemValue="afternoon" />
<f:selectItem id="si_evening" itemLabel="Evening (18:00 - 00:00)"
itemValue="evening" />
</h:selectOneMenu>
<h:outputText rendered="#{selectedPeriodPart eq 'HOURS'}"
value="Hours" />
<h:panelGroup id="hours_spot"
rendered="#{selectedPeriodPart eq 'HOURS'}">
<ui:include src="/includes/reservation/select_hours.xhtml" />
</h:panelGroup>
</h:panelGrid>
</s:div></code>
Note: The calendar value do get passed back to the bean but the value of this piece of code doesn't (it does if you remove the rendered conditional):
