Re: Wicket 1.5 ListMultipleChoice add Serializable values
A DateTimeField does not need the converter to populate a Serializable model:
final DateTimeField txtTime = new DateTimeField("txtTime",
new PropertyModel(this, "objectModel"));
But there are other bugs with it
(https://issues.apache.org/jira/browse/WICKET-4496), so if something will be
done here maybe it will also be necessary to add the converter.
But this is some redundant code. Maybe something will be done in the future.

Re: Wicket 1.5 ListMultipleChoice add Serializable values
Yes Decebal. You are right. If I have a TextField of some type but my model
is a generic one (in my case objectModel is of type Serializable), I have to
overwrite getConverter method like:
final TextField textField = new TextField("txtValue",
new PropertyModel(this, "objectModel")) {
@Override
public IConverter getConverter(Class type) {
return new AbstractConverter() {
public Object convertToObject(String
value, Locale locale) {
return value;
}
@Override
protected Class getTargetType() {
return String.class;
}
};
}
};
This was not necessary in wicket 1.4. Something was changed in converters
area in wicket 1.5

Re: Wicket 1.5 ListMultipleChoice add Serializable values
Maybe you must override TextField.getConverter() because the text field component cannot knows to convert text to object/serializable. -- View this message in context: http://apache-wicket.1842946.n4.nabble.com/Wicket-1-5-ListMultipleChoice-add-Serializable-values-tp4585991p4586299.html Sent from the Users forum mailing list archive at Nabble.com. - To unsubscribe, e-mail: users-unsubscr...@wicket.apache.org For additional commands, e-mail: users-h...@wicket.apache.org
Re: Wicket 1.5 ListMultipleChoice add Serializable values
I forgot to say my object model from TextField is
private Serializable objectModel;
I do not understand how a String is not Serializable?
This code worked on wicket 1.4 without problems. I think something is done
different in wicket framework.
Can you tell me what class throws this error message?
A code like you suggested :
ArrayList list = new ArrayList();
list.add("1");
doesn't even compile.

Hi,
It is pure Java, not Wicket: ArrayList

Wicket 1.5 ListMultipleChoice add Serializable values
Hi.
I have a code that was working in 1.4 but it shows an error message in
wicket 1.5.
I have a TextField, an AjaxSubmitLink and a ListMultipleChoice. When I click
the submit link I want to add the value from text field to the list.
ArrayList list = new ArrayList();
list.add("1");
list.add("2");
list.add("3");
listModel = new Model>(list);
Form form = new Form("form");
final FeedbackPanel feedbackPanel = new FeedbackPanel("feedback");
feedbackPanel.setOutputMarkupId(true);
form.add(feedbackPanel);
final TextField textField = new TextField("txtValue", new
PropertyModel(this, "objectModel"));
final Model> choiceModel = new
Model>();
final ListMultipleChoice listChoice = new ListMultipleChoice("listChoice",
choiceModel, listModel);
listChoice.setMaxRows(100);
listChoice.setOutputMarkupId(true);
AjaxSubmitLink addLink = new AjaxSubmitLink("addElement", form) {
@Override
protected void onSubmit(AjaxRequestTarget target, Form form) {
if (objectModel == null) {
return;
}
ArrayList model = listModel.getObject();
if (objectModel instanceof String) {
try {
if (!model.contains(objectModel)) {
model.add(objectModel);
}
} catch (NumberFormatException ex) {
error("Invalid value type.");
}
}
if (target != null) {
target.add(listChoice);
}
}
@Override
protected void onError(AjaxRequestTarget target, Form form) {
target.add(form);
}
};
form.add(textField);
form.add(listChoice);
form.add(addLink);
add(form);
In Wicket 1.5 I get : "'4' is not a valid Serializable."
I have to use Serializable because I have more components text field, date
field to take the value.
I I use String instead of Serializable, it works.
What is wrong in wicket 1,5?
