> Sometimes, Components don't work as expected when not used with a DOM element.
> This generates bugs, which are often and especially only visible on ajax interaction.
> Common scenario: updating a component via Ajax which is used with wicket:container or setRenderBodyOnly(true). Or updating those (non-existent) DOM element with HTML attributes.
> To allow for fail-fast behavior, I suggest to add an overridable getter to indicate that the component must be rendered as DOM element, e.g. isDomElementMandatory().
