Hello,
But that was it.
The code contained both the
txtName.setOutputMarkupId(true) and the
txtName.add(new AjaxFormComponentUpdatingBehavior("change") { ...
I will paste all the code again (I have now only added the
txtLink.setOutputMarkupId(true) and the TestForm.setOutputMarkupId(true); )
Thank you
==HTML code==
<form wicket:id="testForm">
<table class="contenidoform" cellpadding=1 cellspacing=0 border="0"
width="100%">
<tr>
<th>Name:</th>
<th colspan="3">
<input wicket:id="txtName" size="80"/>
</th>
</tr>
<tr>
<th>
<span><a href="#" wicket:id="clearLink"><img src="images/img.gif"
name="btnClear" /></a></span>
</th>
</tr>
</table>
</form>
==JAVA CODE==
public class TestPage extends WebPage {
private static final long serialVersionUID = 311508940740808005L;
private static final Logger logger = LogManager.getLogger(TestPage.class);
public TestPage(IModel<TestBean> model) {
super(model);
TestForm tst = new TestForm("testForm", model);
tst.setOutputMarkupId(true);
add(tst);
}
class TestForm extends Form<TestBean> {
/**

private static final long serialVersionUID = 1L;
public TestForm(String id, IModel<TestBean> model) {
super(id, model);
TextField<String> txtName = new TextField<String>("txtName", new
PropertyModel<String>(getModelObject(), "name"));
add(txtName);
txtName.setOutputMarkupId(true);
txtName.add(new AjaxFormComponentUpdatingBehavior("change") {
private static final long serialVersionUID = 1654345477970524731L;
@Override
protected void onUpdate(AjaxRequestTarget target) {
target.add(txtName);
}
});
AjaxLink<TestBean> clearLink = new AjaxLink<TestBean>("clearLink", model)
{
/**

private static final long serialVersionUID = 1L;
@Override
public void onClick(AjaxRequestTarget target) {
model.setObject(new TestBean());
TestForm.this.clearInput();
target.add(TestForm.this);
}
};
clearLink.setOutputMarkupId(true);
add(clearLink);
}
@Override
protected void onSubmit() {
logger.info("OnSubmit");
}
}
}
==THE BEAN==
