this is not really feasible. the markup does not contain enough information about the component.
<span wicket:id="name"></span>
doesnt tell me what component i want to put in. is it a label? is it a panel? something else? does it have a default constructor? which constructor to use? which model?
This does give me an interesting idea for IDEA thou - a set of intentions/inspections and maybe a custom auto-completion (not sure how you do that yet thou) that, in the .java file looks up wicket:id's to autocomplete component id params with, and in the .html file, auto complete wicket:id's with unused labels from added components.
A set of inspection/intentions could check hirerachy as well.
Hmmmm - I really should get my JIRA plugin building again but this sounds like an interesting project in itself :)
