[jboss-user] [JBoss Seam] - Submitting using SelectOneRadio

I'm not sure where this should be posted, as it's in a grey area.

I'm using the following reference to submit using a SelectOneRadio.  


Everything works as promised in the example (the listener method is called) but I have one other requirement.  I need to value of the selected radio button to be passed to my listener method.  My locationsByState() listener is traversing a cached list of SelectItems, to return the ones that have a description value of whatever @RequestParameter selectedState is.  The problem is, selectedState is always null.  I think I'm misunderstanding what happens when the commandLink is processed.  I'm assuming the value would be submitted when the commandButton is programatically "clicked."

I have set it up in the Seam action as follows (staticLocations is a globally cached list of locations):

  | private String selectedState;
  | public List<SelectItem> locationsByState(){        
  |         List<SelectItem> locationsByState = new ArrayList<SelectItem>();
  |         loadLocations();
  |         for(int i=0;i<staticLocations.size();i++){
  |             SelectItem current = staticLocations.get(i);
  |             //selectedState is always null
  |             if(current.getDescription().trim().equals(selectedState)){
  |                 locationsByState.add(current);
  |             }
  |         }        
  |         return locationsByState;        
  |     }    

In the view, radioSubmit() is generating a JS event for "hiddenLink", to call the listener method.  Again, everything works exactly as expected.

<h:selectOneRadio value="#{editProfileAction.selectedState}" onmouseup="radioSubmit('hiddenLink');" styleClass="bodyCopy">
  |     <f:selectItem itemLabel="MA" itemValue="MA"/>
  |     <f:selectItem itemLabel="ME" itemValue="ME"/>
  |     <f:selectItem itemLabel="NH" itemValue="NH"/>
  |     <f:selectItem itemLabel="RI" itemValue="RI"/>
  |     <f:selectItem itemLabel="VT" itemValue="VT"/>
  | </h:selectOneRadio>
  | <t:commandLink id="hiddenLink" forceId="true" 
  |     style="display:none; visibility:hidden;"
  |     action="#{editProfileAction.locationsByState}">
  | </t:commandLink>
