> Wicket has a very powerful IComponentResolver interface that allows a
> developer to supply their own IComponentResolver implementation which allows
> component based assembly of pages from a prebuilt collection of panels
> without needing to make hard coded instantiations of the entire set of panels
> into *every* page class that *may* use them. This flexibility is incredibly
> powerful and means that a great amount of page assembly can take place purely
> in the markup.
> Unfortunately any components embedded within a <wicket:enclosure> markup
> </wicket:enclosure> tag (and possibly other 'wrapping' style tags like
> wicket:border) will not trigger the normal 'component resolution' process
> that calls the IComponentResolver implementation and so the children cause a
> 'component not found' page crash unless they are explicitly added to the page
> that will contain them.
> This is extremely undesirable because there can be potentially many, many
> choices of components/panels that can be enclosed. For reasons of
> flexibility, code maintainability, efficient CPU and memory usage it is
> undesirable to add the entire collection of child component candidates to
> every page that could get instantiated with an enclosure in it.
> This bug is trivial to reproduce - set up an IComponentResolver that resolves
> a simple panel, do not add that panel explicitly to a page, but refer to it
> inside a wicket:enclosure tag in the page markup. Display the page in a
> browser.
> I think this would be a fairly straightforward fix for someone who has a good
> understanding of the wicket framework lifecycles. I had a few attempts at
> rectifying the issue but after much trial and error seem unable to locate the
> appropriate place for the 'component resolution' to be triggered.
