Hi
I can see a few things gond wrong here...
1> First in the onclick method , this does not refer to the original parent
to which label was added initially as label is the component u want to
replace
2> When u want to add a new component to replace the original component
in the parent heirarchy , u need to call replace method or replaceWith
method
3> Dont create the textfield right at the beginning. Do it in the onClick
method.
Here it just hangs out there until user clicks the link

Hi,
I want to change a component in html, for example:
*1)Test.html*
<html>
<body>
<span wicket:id="label"></span>
<br/>
<a wicket:id="ajaxLink">Click here</a>
</body>
</html>
*2)Test.java*
public class Test extends WebPage {
private int count = 0;
Label label = null;
TextField textField = null;
public Login() {
super();
label = new Label("label", new PropertyModel(this, "count"));
label.setOutputMarkupId(true);
textField = new TextField("label", new PropertyModel(this,
"count"));
textField.setOutputMarkupId(true);
AjaxLink ajaxLink = new AjaxLink("ajaxLink") {
public void onClick(AjaxRequestTarget request) {
count++;
if (count % 2 == 0)
{
this.add(label);
request.addComponent (label);
}
else
{
this.add(textField);
request.addComponent(textField);
}
}
};
this.add(label);
this.add(ajaxLink);
}
public int getCount() {
return count;
}
public void setCount(int count) {
this.count = count;
}
}
However, when I client the link, the Ajax message shows as:
INFO:
INFO: Initiating Ajax GET request on
/wicket/mytest/?wicket:interface=:0:ajaxLink::IBehaviorListener&wicket:behaviorId=0&random=
0.17448336090136768
