The IDE makes a suggestion (also known as a "hint") about what to do to fix the problem. When you click on the suggestion in the screenshot above, you find this on the HTML side:
As before, of course, the suggestion that the IDE offers depends on the component type as well as the context within the hierarchy of Wicket components. Currently, since this is really a prototype, the above tag is just added below the opening BODY tag.
We're going to continue working on this, but since it is not our official work, we're forced to do it in our spare time, which doesn't make the resulting module develop very fast. This is also why we've open sourced the Wicket module for NetBeans. The sources aren't available yet, but the java.net site is up and functioning (albeit currently a bit bare). So, if you're a Wicket user, you're completely free to "timmer aan de weg" (as one says in Dutch). Here's the link, once our sources are up there, we'll let you know (via this blog):
We're looking for volunteers for this worthwhile project! Could YOU (yes, you) be one of them?
