DataTable, ChoiceFilteredPropertyColumn, Choice renderer and values translated via M:1 association

[Petr Fejfar <pe...@gmail.com>]

Hi all,

please, could somebody push me forward how to implement ChoiceRenderer
of ChoiceFilteredPropertyColumn? I seem to be lost among data
providers and models little bit...

I followed Wicket-stuff's phonebook example and I show list of
persistent entities in the DataTable. I'd like to have a choice
filtered column containing subcription names got from phone numbers
via @ManyToOne association. But I'm not able to create proper Choice
renderer to be returned to DataTable for filtering purposes. My code
looks like this (choice filtering is commented out):


    private PropertyColumn<String> createSenderColumn()
    {
        return new PropertyColumn<String>(new
ResourceModel("columnPhone"), "phone", "phone") {
//        return new ChoiceFilteredPropertyColumn(
//                new ResourceModel("columnPhone"), "phone","phone",
//                new LoadableDetachableModel() {
//                    private static final long serialVersionUID = 1L;
//                    @Override
//                    protected Object load() {
//                        List names =
TTraceWebSession.get().getUser().listSubscriptionNames();
//                        names.add(0,"");
//                        return names;
//                    }
//                }) {
            private static final long serialVersionUID = 1L;

            public void populateItem(Item cellItem, String
componentId, IModel model) {
                AttitudeHistory history = (AttitudeHistory) model.getObject();
                Label label = new Label(componentId, createLabelModel(model));
                label.add(new AttributeModifier("title", true, new
Model<String>(history.getPhone())));
                cellItem.add(label);
            }

            @Override
            protected IModel createLabelModel(IModel rowModel) {
                final AttitudeHistory history = (AttitudeHistory)
rowModel.getObject();
                return new AbstractReadOnlyModel<String>() {
                    private static final long serialVersionUID = 1L;

                    @Override
                    public String getObject() {
                        return history.getSubscription().getSubscriptionName();
                    }
                };
            }

//            @Override
//            protected IChoiceRenderer getChoiceRenderer() {
//                return null;
//            }


            public String getCssClass() {
                return "column-phone";
            }
        };

    }


Thanks, Petr
