OptionSelector problem

[Mick21367]

Hi,
I've had a problem with the OptionSelector on the LocalRadio app ever since I introduced filters. Basically, if I select one of the filters (say BBC Local Radio) and then select one of the stations from the OptionSelector, the OptionSelector then displays a different station - even though the app plays the correct station. Some of the other stations display a blank instead. Does anyone have any idea where I'm going wrong? The code for the filter and OptionSelector are below:-
// This is the filter I apply to limit the results shown in os1

    ListModel {
       id: filterModel
    ListElement {
       name: "Radio"
       }
    ListElement {
       name: "BBC National Radio"
       }
    ListElement {
       name: "BBC Local Radio"
       }
    ListElement {
       name: "BBC International Radio"
       }
    ListElement {
       name: "Independant National Radio"
       }
    ListElement {
       name: "Independant Local Radio"
       }	
    } 

// Filter OptionSelector

 OptionSelector {
        id: os2
        containerHeight: units.gu(90)
        width: parent.width
        model: filterModel
        onClicked: view.model.reload(filter)
        }

// this is the List shown in the Channel OptionSelector

     XmlListModel {
        id: model
        source: "src/stations.xml"
        query: "/stations/station"
          XmlRole { name: "index"; query: "index/string()"}
          XmlRole { name: "type"; query: "type/string()" }
          XmlRole { name: "name"; query: "name/string()" }
          XmlRole { name: "link"; query: "link/string()" }
          XmlRole { name: "play"; query: "play/string()" }
          XmlRole { name: "icon"; query: "icon/string()" }
          }
    SortFilterModel {
        id: sortedRadio
        model: model
        filter.property: "type"
        filter.pattern: new RegExp(filter.text)
        }

// this is the Channel Selector

   OptionSelector {
       id:os1
       containerHeight: 300 - units.gu(1)
       model: if (favText.text==1) {
                  favourites
              } else {
                  sortedRadio
              }
       delegate: OptionSelectorDelegate { text: name; subText: type}
   }

Thanks
Mick
