[jira] Commented: (WICKET-3263) Allow AjaxRequestTarget.IListeners to be Registered at the WebApplication Level

["Martin Grigorov (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/WICKET-3263?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12972841#action_12972841 ] 

Martin Grigorov commented on WICKET-3263:
-----------------------------------------

I don't like that now we have both #newAjaxRequestTarget(Page) and setAjaxRequestTargetProvider().
AjaxRequestTarget is not quite extendable. I think #newAjaxRequestTarget() is public just because it is called from another package (org.apache.wicket.ajax.AbstractDefaultAjaxBehavior.onRequest()).

I suggest to either leave it as it is now + the listeners, or to extract interface IAjaxRequestHandler that extends IRequestHandler and AjaxRequestTarget is the default impl + the provider and listeners.

> Right now, in order to register an AjaxRequestTarget.IListener, you have to override WebApplication.newAjaxRequestTarget(Page p).  That does make Wicket very "pluggable."  What if multiple frameworks need to add in that hook?  So, why not allow a global, application-level, registry of those listeners.  Each AjaxRequestTarget would have those listeners added to it.
