Hi Bart
I see you added a behavior to deal with Dojo widget creating it using
dojo.widget.createWidget. I don't understand what is the aim of this
abstract behavior because AbstractRequireDojoBehavior can already create
a dojo widget via an AjaxRequestTarget (see TargetRefresherManager which
is a listener on ajaxRequest Target) but I maybe miss something.
The way we choose to create dojo widget in Wicket is adding parameters
on the component tag. AbstractDojoWidgetBehavior deals with
dojo.widget.createWidget and extending AbstractRequireDojoBehavior the
widget created with this behavior could be added twice in the dojoManager.
On the other hand it will be great to keep a unique way to create widget
in WCD. I'm not saying the way we use now is the better but it can be
better if we use always the same (adding attribute on component tag OR
using dojo.widget.createWidget).
Just say me if I simply not well understand the goal of this class ;) .
Otherwise we need to choose a *unique* way to render dojo widget and
apply it on all widgets.
