Sending JSF parameters within Richfaces a4j:repeat

[seamnewbie]

I'm attempting to put a few drop down menus inside of an a4j:repeat. The values for the second drop down are dependent on the value selected in the first. Below is the code I am attempting to use, but it passes a blank parameter:

<a4j:repeat id="localRepeat" var="local" value="#{InstanceController.instance.locations}" rowKeyVar="row">
 <h:panelGrid columns="2">
 <h:outputLabel value="Theater:" />
 <h:selectOneMenu id="theater" converter="#{TheaterConverter}" value="#{local.theater}">
 <f:selectItems id="theaters" value="#{InstanceController.allTheaters}" />
 <a4j:support event="onchange" action="#{InstanceController.getAllCountriesInTheater}" reRender="country" >
 <f:param name="theater" value="#{local.theater.id}"/>
 </a4j:support>
 </h:selectOneMenu>

 <h:outputLabel value="Country:" />
 <h:selectOneMenu immediate="true" id="country" converter="#{CountryConverter}" value="#{local.country}">
 <f:selectItems value="#{InstanceController.allCountriesInTheater}" />
 <a4j:support event="onchange" reRender="state" />
 </h:selectOneMenu>

 </h:panelGrid>
 <rich:spacer height="10px" />
 </a4j:repeat>

If I change the f:param to send "1" instead of "#{local.theater.id}" it works as expected.

Is there a way to get the selected value of the first drop down and send it as a parameter?

Hi,

This should work ok. Probably,

#{local.theater.id}

is null initially, that's why it's not being sent.

Ok, I've initialized local.theater so it isn't null initially. Unfortunately my parameter never gets changed when local.theater is updated. So regardless of what I select in the first drop down, I get the same values in the second.

- Add rich:messages and check if there are any generated
- Check example of linked dropdowns at livedemo.
