i have a question: how can i comunicate between panels in wicket?
The normal Wicket way is to share models, pass references etc,
but it has its limitations.
You can find an example of a push-type mechanism here
https://issues.apache.org/jira/browse/WICKET-1312
though it is done with just one page in mind.
This patch is almost what I want, cool!
A question though: When sharing models between components, or using
PropertyModels on a shared model, I would like to have onModelChanged
events when something in that model changes. That way Components that
use the model could use the onModelChanged method to add themselves to
the AjaxRequestTarget (using AjaxRequestTarget.get() or
(RequestCycle.get().getRequestTarget() instanceof AjaxRequestTarget) in
wicket-1.2.x). Unfortunalety onModelChanged is only called when a model
or model object is explicitly set on a component.
Is there a way to make this more transparent? I was thinking along the
lines of adding PropertyChangeSupport to all my model objects, but that
would be very laborious. An aspect-oriented solution might do the trick too.
Any ideas?
