Here what I did:
choiceComponent in the original Palette is private, so in my custom palette
I externalized it:
private Component externalizedChoiceComponent;
Then, I overridden the method newChoicesComponent :
@Override
protected Component newChoicesComponent() {
final Component result = super.newChoicesComponent();
externalizedChoiceComponent = result;
externalizedChoiceComponent.setOutputMarkupId(true);
return result;
}
public Component getExternalizedChoiceComponent() {
return this.externalizedChoiceComponent;
}
My situation was that I wanted to change the choices with a DropDown
component.
We have a custom DropDown that is ajaxified:
final DropDownChoice configurationChoice = new
DropDownChoiceWithAjaxIndicator("mainConfiguration",
getConfigurationsModel(), new
ChoiceRenderer("configurationName", "configurationName")) {
private static final long serialVersionUID = 1L;
@Override
public void updateOnChange(AjaxRequestTarget target) {
target.addComponent(palette.getExternalizedChoiceComponent());
}
};
Below is the IModel for the palette that needs to be changed:
final IModel allConfigurationsModel = new AbstractReadOnlyModel() {
private static final long serialVersionUID = 1L;
@Override
public Object getObject() {
// Do whatever you want to get the correct choices
}
};
And this is the Palette creation:
final CustomPalette palette = new CustomPalette("palette", new
PropertyModel(rolesCoverageDasboard,
"comparedConfigurations"), allConfigurationsModel,
choiceRenderer, 10, true);
Is this what you need?
BTW,
I think I'll have a look at the Recorder, though I'm not sure I can use it.
Maybe we should open a JIRA to have getChoicesComponent() in the Palette?
(we use 1.3.6)
