Hi,
Can someone please explain to me what's causing this exception (see end
of this mail) when trying to add a component to an ART ?
In
http://apache-wicket.1842946.n4.nabble.com/Components-can-no-longer-be-added-td4662838.html
Sven Meier said
once rendering of components via Ajax has started, you cannot update
components.
but as can be seen from the stacktrace I'm still in the beforeRender()
phase ... or is anything inside the beforeRender() code path already
considered to be part of the rendering phase ?
Thanks,
Tobias
