Examples of org.wicketstuff.select2.ChoiceProvider

org.wicketstuff.select2.json.JsonBuilder
Acts as a bridge between Select2 components and the application's domain model.

The two important services provided by implementations are:
- Feeding choices, represented by the application's domain objects, to Select2 components
- Transcoding said choices to and from Json so they can consumed by Select2
For the most common usecase where each choice is rendered as a text string see {@link TextChoiceProvider}.
@author igor @param < T> type of choice object

      value = getModelObject();
    }


    if (value != null) {


      JsonBuilder selection = new JsonBuilder();


      try {
        selection.object();
        getProvider().toJson(value, selection);
        selection.endObject();
      } catch (JSONException e) {
        throw new RuntimeException("Error converting model object to Json", e);
      }
      response.render(OnDomReadyHeaderItem.forScript(JQuery.execute("$('#%s').select2('data', %s);", getJquerySafeMarkupId(),
          selection.toJson())));
    }
  }
