Apparently, when the page is loaded using the cache (at least I think so), it still gets the 'sortedColumnedChildren' property from the entities, which shouldn't be the case if the page was static, so I guess it's not cached correctly after all... Might be nothing, but at the bottom of the page, I have a '~facelets.VIEW_STATE~' line, dunno where it comes from.
