I implemented a simple IComponentBorder, and anything I put in the
beforeRender gets added again every time I try to update the component
with AJAX.
My IcomponentBorder has:
public void renderBefore(Component component)
{
Response resp = component.getResponse();
resp.write("Label");
}
To update the input box using AJAX I have a behavior:
Input1.add(new AjaxFormComponentUpdatingBehavior("onchange")
{
protected void onUpdate(AjaxRequestTarget target)
{
theItem.name="new value";
target.addComponent(input2)
}
});
When I do target.addComponent(input2), the renderBefore adds "Label"
again, so the HTML looks like:
Label Label <input wicket:id="input2"/>
Am I using IComponentBorder wrong?
Thanks for any help!
