hi,
i need to display/update some boolean properties in my domain model.
to achieve that i'm using a custom AjaxEditableChoiceLabel (from
wicket extensions) in my user interface.
why dropdown and not checkbox? well, because in fact there are 3
choices for this property in the database: true (yes), false (no),
null (unknown). my problem comes here: i'm having a bad time figuring
out how to "translate" between Boolean.TRUE, Boolean.FALSE, null and
yes, no, unknown.
at first i thought it should be enough with a converter, so i overrode
that in my custom dropdown:
class CustomAjaxEditableChoiceLabel extends AjaxEditableChoiceLabel {
public CustomAjaxEditableChoiceLabel(String id) {
super(id, Arrays.asList(Boolean.TRUE, Boolean.FALSE,
null));
}
@Override
protected void onEdit(AjaxRequestTarget target) {
if (VdWebSession.get().isAuthenticated()) {
super.onEdit(target);
}
}
@Override
protected void onSubmit(AjaxRequestTarget target) {
super.onSubmit(target);
repo.persist((Doctor)getParent().getModelObject());
}
@Override
public IConverter getConverter(Class type) {
return new CustomBooleanConverter();
}
}
...and the converter
public class CustomBooleanConverter implements IConverter
{
@Override
public Object convertToObject(String string, Locale locale) {
if (string.equals("yes")) {
return Boolean.TRUE;
} else if (string.equals("no")) {
return Boolean.TRUE;
} else {
return null;
}
}
@Override
public String convertToString(Object object, Locale locale) {
if (object == null) {
return "unknown";
}
Boolean b = (Boolean) object;
if (b) {
return "yes";
} else {
return "no";
}
}
}
and i'm instantiating the component like this:
setModel(new CompoundPropertyModel(doctor));
(...)
add(new CustomAjaxEditableChoiceLabel("free").setOutputMarkupId(true));
this is working very well, except for the labels when i enter the
dropdown mode.... i still see "true", "false", (blank). i want my
labels also to be displayed when entering in "edit mode".
i read about IChoiceRenderer and i even implemented one, but i can't
use it with the CompoundPropertyModel (?).... cause in my component
constructor i can't do
super(id, Arrays.asList(Boolean.TRUE, Boolean.FALSE, null), new
CustomDropDownRenderer());
(i need to pass in a Model, which is not updated as it is with the
compound one. or how would you do?)
i would really appreciate some hints/ pointers; i've lost time with
this "little" issue. thanks in advance!
