thanks Matthijs,
Your understanding of the problem is correct, we are trying to generate a
HTML pages at runtime. But the solution proposed is looks quiet complicated.
I guess there is no easy way in Wicket to achieve this. so still we are not
able to get the right solution yet.
I was thinking on the lines provided by you. If I can generate some dynamic
content using IMarkupResourceStreamProvider.getMarkupResourceStream(), like
for example a image tag then how am I suppose to add this markup in the
corresponding java class.
