Very strange exception

Hello guys, I get this exception, when loading a page:

WicketMessage: The component(s) below failed to render. A common problem is that you have added a component in code but forgot to reference it in the markup (thus the component will never be rendered).

1. [Component id = label]

Root cause:

org.apache.wicket.WicketRuntimeException: The component(s) below failed to render. A common problem is that you have added a component in code but forgot to reference it in the markup (thus the component will never be rendered).

1. [Component id = label]

     at org.apache.wicket.Page.checkRendering(Page.java:1162)
     at org.apache.wicket.Page.renderPage(Page.java:922)
     at org.apache.wicket.request.target.component.BookmarkablePageRequestTarget.respond(BookmarkablePageRequestTarget.java:262)
     at org.apache.wicket.request.AbstractRequestCycleProcessor.respond(AbstractRequestCycleProcessor.java:105)
     at org.apache.wicket.RequestCycle.processEventsAndRespond(RequestCycle.java:1258)
This looks some kind of fake, as long as I don't have any components with id=label. Also I examined the catalina.log and found nothing relative to this.
Can someone shed more light on this?

Thanks in regards,
Martin

I found it! That label was missing in my set access denied page. I had to click on the display page link in the bottom to see where this happens.

Thank you all!
Regards,
Martin

I have used id="label" a lot in my pages/components, so I don't think
that's your problem.  Are you sure your label is set up in your markup
in the right spot (in the hierarchy)?

Hi, Wilhelmsen!

Yes, this is pretty clear. I've got enough experience in order to know this :) Maybe the problem is the wicket:id, which I've named 'label'. Maybe this is problem, since I heard certain 'ids' cause problems, like buttons with id=submit, links with id=link and so on.

Thank you, anyway!

Regards, Martin

When you do

add(new Label("label", ...

in a Page, you also need something like

<span wicket:id="label">This gets replaced</span>

in your HTML template.
