Hi Martin, consider this form:
java code:
Form form = new Form("form");
add(form);
final TextField<Integer> textField = new TextField("tf", new
Model());
textField.setType(Integer.class);
textField.setOutputMarkupId(true);
form.add(textField);
AjaxLink link = new AjaxLink("reload") {
public void onClick(AjaxRequestTarget target) {
IModel referenceToModel = textField.getDefaultModel();
referenceToModel.setObject(new Integer(30));
target.addComponent(textField);
}};
form.add(link);
form.add(new FeedbackPanel("fp"));
markup code:
<form wicket:id="form" >
<input wicket:id="tf" type="text" />
<a wicket:id="reload">reload</a>
<input type="submit" />
<div wicket:id="fp" ></div>
</form>
In the browser:
1 - you type something wrong on the text field, like some non numeric
characters
2 - submit the form. At this moment, you has your forms components on the
server with the raw input
3 - press reload link, to change the value on the text field model
4 - you has now an text field presenting the wrong user typed value, and the
new one on the component model on server.
