Re: How to make img src in a component's template resolve to the image files in the package?

so if that is all it does why does it need to be a component?

also you shouldnt keep references to Class objects in your components,
app server will have trouble restarting the app when it tries to
unload it...so keep the class name instead

as far as having something like this by default in wicket, and this is
my personal opinion, your class only has 2-3 lines of code that
actually do anything, so i would say it is trivial. i can come up with
at least 10 trivial classes that have to do with images off the top of
my head, if we put them all into wicket it will get very cluttered
very quickly. so i would say, no, it takes 10 minutes to write one.
