Peter Parson created WICKET-4978:
------------------------------------
Summary: Add possibility to force usage of (renderable) tag for
own Components
Key: WICKET-4978
URL: https://issues.apache.org/jira/browse/WICKET-4978
Project: Wicket
Issue Type: Bug
Components: wicket
Reporter: Peter Parson
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().
