Re: [Wicket-user] What about Wicket Javascript and Browser errors?

[Igor Vaynberg]

you cannot add a new component via an ajax call because wicket will not know where to put its markup. via ajax you can only replace components that have been previously renderered.

so in your case if you wanted to replace the Label you would do something like this

final Label label;

add(label=new Label("a", "A"));

label.setOutputMarkupId (true); <=== this is important if you want to rerender this component via ajax

 add(new AjaxLink("link") {
     public void onClick(AjaxRequestTarget ajaxRequestTarget) {
        Label b = new Label("a","B");

        label.getparent().replace(b);

        ajaxRequestTarget.addComponent (label);
     }
 });
