Ernesto Reinaldo Barreiro commented on WICKET-5087:
---------------------------------------------------
@Martin,
Apologies for my late reaction!
I think this is a nice feature to have. In essence it is like mounting a
"global router" on a page.
About uniqueness of URL. Maybe we can add a
/**
* Determines if it can handle a "short URL" AJAX request.
*
* @param target
* @return returns true by default.
*/
public boolean canHandleShortUrlRequest(AjaxRequestTarget target)
{
return true;
}
Which can be used to discriminate components having same short URL. See
attached patch + example
Also
1- I would try to experiment with this creating a complex UI widget to see how
useful this really is: I can try to volunteer and do that.
2- Another feature that might be nice to have is mounting "stateless non
synchronized resources" on the fly, maybe associated to the page, so that
components could attach some stateless "services" to a page
and use page as context for serving them.
Cheers,
Ernesto

> Key: WICKET-5087
> URL: https://issues.apache.org/jira/browse/WICKET-5087
> Project: Wicket
> Issue Type: New Feature
> Components: wicket
> Affects Versions: 6.6.0
> Reporter: Martin Grigorov
> Assignee: Martin Grigorov
> Attachments: WICKET-5087.patch, wicket-ajax-shorturl.tgz

>
> Many JavaScript libraries require server endpoint for making requests for
> loading/saving data.
> To integrate such JS library with Wicket the application developer should
> make the IRequestListener's url available as an endpoint. That is it need to
> store somewhere the url produced by #urlFor() or
> AjaxBehavior#getCallbackUrl().
> This new feature will make this much simpler for the application developer.
> A new method will be added to Wicket.Ajax namespace to facilitate this:
> Wicket.Ajax.short({
> 'su': 'countries',
> 'dep': [function() {return [{'name': 'extra', 'value': 'param'}]}],
> 'coh': [function() {console.log('Completed!')}]
> });
> This new method will again receive an object with all possible attributes
> plus a new one - 'su', stands for 'short/stable/simple' url.
