Table with a lot of ajax links
Hi guys,
I am making table of some items. Table component is default wicket
DataTable. Table page size is 100 items per page and data have several
pagings. So that is easy.
Now I would like to add 5 ajax links related to row item. That is also no
problem and easy and everythings works fine.
But when I exploring page rendered HTML source, I see a lot of ajax event
bindings. (exactly 500 = 100 * 5)
Wicket.Ajax.ajax({"u":"./links?2-1.IBehaviorListener.0-c1~link","e":"click","c":"id4"});;
Wicket.Ajax.ajax({"u":"./links?2-1.IBehaviorListener.0-c2~link","e":"click","c":"id5"});;
....
I understand how it works, but I would like to ask if you know some solution
how reduce large amounts of events binding, because I am affraid about page
loading performance with this huge count of bindings.
Thanks for your advice.
Dave

Hi,
you can have a look at what Martin Grigorov is doing on https://issues.apache.org/jira/browse/WICKET-5267. It's exactly what you are talking about.

I can also try to pack the project as a jar file (so, that is is reusable)
and move it to wicket-stuff or some other place that gets regularly
published.

Hi,
Thanks for the feedback.
In fact, solution can be improved in many aspects. For instance, I thought
about making the "logic" pluggable so that you can support more that just
links... Maybe having a "handler" interface that can be registered on
"context" component and is responsible for
1- The header contributions needed by the "links". I write "links" because
they might be anything.
2- A method to decides is a particular AJAX request can be handled by the
given handler.
3- A logic to deliver the event to the appropriate component(s).
This way we might have something "generic" and "extendable". For instance,
that could be used to register drag-drop events or anything you need.
If interesting to other people I can give it a try to this idea and publish
the code (and try to write something to explain the design). Mind example
is a table but behavior can be attached to "any" component.

Thank you very much, Ernesto.
I have a similar scenario, a panel with about 300 AjaxFallbackLinks and
each with some custom logic on the onClick, but your solution looks much

The same approach was used for things like dragging cells around... and
many other dirty tricks... If you do this in an organized manner you could
still have something that is not 100% the wicekt way but still have some
nice "componentization".
As Cedric said martin is working to deliver something generic.

Hi,
For some application with very big tables with lots of links and AJAXy
things I have done the following.
1- Place a an AbstarctAjaxBehavior at table level.
2- Create special link components that all what they do I submit info about
their ID to this unique AbstarctAjaxBehavior.
3- On server side you can use a visitor, on unique AJAX behavior, to
locate the instance of the "special link" and deliver the event to it.
This reduced a lot the amount of java script to stream to the client and
made component very responsible.
