Hi,
Thanks for your reply.
I'm familiar with wicket (reasonably anyway), that may not have been clear from the post.
The admin of the CMS system is all using wicket, and I'm fairly happy with that.

The situation is where the CMS content template pages are unknown in structure, but I just want to be able to insert a marker into the page to replace certain values (as I'm not sure which component the references may be in - ie in the src attribute of an img tag, or in a parameter passed to some javascript etc), so I can't map wicket components to the dynamic content.

I've noticed the wicket velocity and wicket freemarker contrib projects, would these accomplish what I want?

I still want to have the functionality of wicket (which is great), but just want to be able to do effectivley some global replaces on the generated html markup to replace some markers with actual values.
Hope that makes it a little clearer.
Cheers
Andrew

Hi Andrew,

Your use-case is exactly what Wicket is about. In the template file, use
wicket:id attributes on the img tag. Place these tags in some kind of
container (span or div element) to be able to repeat it. In the code you
can attach an instance of Image (or variations, see javadoc). Use a
ListView or Repeater to repeat the images.

You can find more information in the javadocs and on the Wiki. In
particular
http://cwiki.apache.org/WICKET/newuserguide.html,
http://cwiki.apache.org/WICKET/listview-and-other-repeaters.html and
http://cwiki.apache.org/WICKET/how-to-load-an-external-image.html.

Regards,
Erik
