Subject [jira] Commented: (CLK-543) SimpleLink control.
Date Fri, 22 May 2009 08:46:45 GMT


Adrian A. commented on CLK-543:

and updating the

Most important of course, would be the functionality, so if it includes the above snippet
than it would be an improvement to the actual situation. Because of the "historical naming"
however, many users won't "guess" to use it.

Of course, a much better approach would be to refactor e.g. AbstractLink to Link (and make
it non-abstract). Since it's abstract, users don't use it directly, so most of them won't
be affected. IMHO Click should be as intuitive as possible, and in the case of a link, there's
nothing more intuitive than "Link" :).

> There doesn't seem to be any "simple link" control in Click to be  able to point to an
arbitrary URL (internal but external too).
> There's now the ExternalLink but it's just too specific :( - extending it would conflict
with it's name (maybe a rename would be better).
> In many cases there's no distinction in the application between an internal an external
URL (e.g. because the external might be a subdomain).
> Another problem is that AbstractLink is can't be used directly for these simple cases
(being abstract).
> Basically a SimpleLink code would look like ExternalLink, but it would have this additional
snippet after L:106:
> <code>
>         String ctxPath = getContext().getRequest().getContextPath();
>         if(!getTargetPath().contains("://")) {
>             buffer.append(ctxPath);
>         }
> </code>
> This would allow to use only one control, and in the application logic, depending on
the target, to let the control itself render the required context path if needed.
