Igor Vaynberg resolved WICKET-4408.
-----------------------------------
Resolution: Won't Fix
Assignee: Igor Vaynberg
auto components cannot contribute to the header. they are processed at render
time, after the header would have already been rendered. resolved components
are meant for simple stateless components such as ones handling the
wicket:message tags, nothing more.
depending on your usecase, if you need automatically resolved components you
may wish to do your own resolving in oninitialize() where markup is available.
walk the markup and add components based on it.

> Key: WICKET-4408
> URL: https://issues.apache.org/jira/browse/WICKET-4408
> Project: Wicket
> Issue Type: Bug
> Components: wicket
> Affects Versions: 1.5.4
> Environment: Happens on all FireFox Chrome, IE
> Windows XP
> Reporter: Chris Colman
> Assignee: Igor Vaynberg
> Labels: wicket
>
> If a component is resolved via an IComponentResolver implementation then its
> overridden renderHead method never gets called.
> If the same component is added explicitly to its parent then its renderHead
> method is called.
> This is critical for us because we have markup variations that may or may not
> include certain panels. We thus leave the construction/adding of these panels
> to our IComponentResolver implementation because we can't explicitly add them
> because not all markup will require all panels.
> Class MyPanel extends Panel
> {
> /**
> * Write out necessary header markup.
> */
> @Override
> public void renderHead(IHeaderResponse response)
> {
> StringBuffer sb = new StringBuffer();
>
> sb.append("<script src=\"/jquery.easing.1.3.min.js\"></script>");
> sb.append("<script src=\"/trans-banner.min.js\"></script>");
>
> response.renderString(sb.toString());
> }
> }
> We aren't using any markup inheritance at the panel level.
