Just wondering if it would be possible and if so, worthwhile, to have a 'validation' point somewhere in the (development) page processing, to try & warn about things that are valid but probably not what's intended.
The specific issue that springs to mind is that raised in WICKET-1163, i.e. where you have a component that's had both setVisible(false) and setOutputMarkupId(true) called on it, but not setOutputMarkupPlaceholderTag(true). It seems to me that that it might be worth a warning in the log file when in development mode, at least, and there might be other combinations that might be worth detecting.
