I think this is the most helpful reply. A static image will be linked
successfully this way.
Thanks for the nice sharing. It helps a lot.

The context image looks nice, but I cannot use it in a ClientSideImageMap -
is that on purpose?

For now UrlResourceReference serves my purpose.

Thank you for helping

Re: Static image

[Martin Grigorov]

Hi,

Here is the source of
org.apache.wicket.markup.html.image.Image#getStatelessHint()
{
return (getImageResource() == null || getImageResource() ==
localizedImageResource.getResource()) &&
 localizedImageResource.isStateless();
}

I.e. if the image uses a IResource then it is stateful because the url to
the IResource is dependent on the component (e.g.
?2-IResourceListener-container~image).
If you use ResourceReference then the url to reach it doesn't depend on the
page/component (e.g. wicket/resource/).

As Andrea mentioned you can use ContextImage which also doesn't use
IResource and the generated url doesn't depend on the page/component.

Re: Static image

[Andrea Del Bene]

Have you tried with ContextImage?

Hi - I would like to link to a static image, and the link should be
stateless.

I have tried this (using Scala):

val img = new Image("img", new ContextRelativeResource("images/img" + imgId
+ ".png"))

But the link becomes stateful.

I just found

val img = new Image("img", new UrlResourceReference(new Url(listOfStrings,
Charset.defaultCharset(

Is the last example the preferred way of achieving this?

Thanks in advance,
René
