Ok, it doesn't look like I'll have time to work on this for a while :( If I do get around to it, at least now I know where to start.
Thanks anyway, Gili

no, autolinks don't use <wicket:component>. See src/test/wicket/markup/html/link/AutolinkTest for examples. The implementation of autolink is twofold. a) detect <a href> and make them a component, though they don't have wicket:id and b) handle these "special" components (implements IComponentResolver)

Is this how you implemented <a href> autolink or is there a better way? How difficult would it be to implement a static image autolink?
Thanks, Gili

Please see src/test/wicket/markup/ComponentCreateTagTest and the associated files for how to use <wicket:component>. This feature is still marked experimental, but it is in core.

Hmmm... yes... you could be right actually.

Interesting. I thought that <wicket:component> was never implemented. Didn't we defer it to 1.1 and ripped it out of the 1.0 engine? Juergen is there any supporting documentation on how to use this thing? How do we deal with the parenting issue, etc?
Thanks, Gili

Yep. There were a lot of changes the last few weeks. Good news is that that's really finally over now. We'll put 1.0RC1 out when Jonathan is back home, this week. He worked on a few articles as well. The article he planned on writing in the airplane was about resources. So hopefully, things will get clear from his piece then.
You're right about that it is doable to parse a tag and create a resource from it. Why not take a look and see if you can do it? If you use the <wicket:component.. stuff Juergen build, you should be able to do this quite easily is my guess.

Sorry Eelco, I still don't see it. I am simply not familiar enough with the details of clustering and the core code has been shifting so much recently I find it difficult to keep up-to-date with Wicket's paradigm-of-the-day. If we can invoke this code manually, I don't see why you can't invoke it automatically at parsing time. We have access to the Application and are capable of ensuring the resource is only generated the first time and all the other things you mentioned. In so far as I understand, the process is 100% reproducible so clustering is not a concern. You just need to ensure that the same resource path will always result in the same static image URL (regardless of which machine computes it), and that is certainly possible to implement. If I have missed something, please explain the problem in more detail; it'll likely help me understand
Thank you, Gili

Efficiency and clustering. Look at the code. In application the 'stable' url to the resource is created. But only if not done yet. Furthermore, to have clustering work, the action of creating/ getting the resource must be reproducable.

I'm not familiar with Application.getSharedResource() and all the new methods you mention, but can you please explain why you can't pick up the factory and static name automatically? Aren't there decent defaults for both these things?

As a side node this is what you can do to use static images now:
private SharedResource getImage(final String name) { return getApplication().getSharedResource(MyTree.class, name, new ISharedResourceFactory() { public Resource newResource() { return StaticImageResource.get(MyTree.class.getPackage(), name, null, null); } }); }
Image img = new Image(NODE_IMAGE_NAME, getImage("node.gif"));
In the above piece of code, 'node.gif' will be read from the package (could be from a jar) and used as the resource for the image. A static URL is created for it, based (in this case) and the package name and the given name ('node.gif').
It probably won't get easier than this, as we need the factory and static name to be able to support clustering. Actually, I think it really rocks that we can support this in a clustered environment now. Not many other frameworks that'll do that for you ;)

I'm looking for some feedback on how difficult it would be to implement this. It has been filed as a RFE a week back I think. If it is trivial, I am hoping we can schedule it for pre-1.0. Right now it is rather annoying doing it manually (but at least it's doable). One of my pages had twelve static images and adding them in took me a long while. If we can automate this sort of thing I really think we should.
