repopulating a Object Select

[Eldred Mullany]

Hi all 

 

I know this topic of conversation has sprung up many times and I feel a
bit stupid asking. I have an eventHandler method that returns an object.
I have looked at the wiki regarding the GenericSelectionModel and have
implemented it in my own class, however I get classCast Exceptions: 

 

za.co.easypay.web.tapestry.core.model.GenericSelectionModel cannot be
cast to [Ljava.lang.String; [at context:collector/Search.tml, line 18]

 

Here is my method that is called onChange event: 

 

public Object onProvideValues(String input) {

      

      List<String> locations = new ArrayList<String>();

      

      this.locationList =
getChildrenLocations(this.encoder.toValue(input));

      

      for(Location loc : this.locationList) {

          locations.add(Integer.toString(loc.getID()));

          locations.add(loc.getName());

      }

      

      GenericSelectionModel locationModel = new
GenericSelectionModel(locations, "name", propertyAccess);

      return locationModel;

    }

 

 

..and here is my t:model method that initially populates my select
component when the page loads which works fine: 

 

public SelectModel getModel() {

      

      try {

          this.locationList =
this.easypayConfigService.getAllMerchantGroups();

      

      } catch (LocationTypeNotFoundException e) {

          // TODO Auto-generated catch block

          e.printStackTrace();

      }

      GenericSelectionModel locationModel = new
GenericSelectionModel(this.locationList, "name", propertyAccess);

      return locationModel;

    }

 

I have overlooked something obvious here?

 

Thank you
