Component self updating when Ajax call changed a commun model ?

[ZedroS]

Hi

I've the following issue : in a panel a checkbox needs to be disabled depending on a "ajax updated" list in a sub panel (if there is something in the list the checkbox is disabled).

Currently I give the checkbox reference to the other panel and then use it in the sub panel "add" AjaxLink.  

However, I will have soon more components on which this checkbox will depend for its state (lists in other sub panels).

As such, I wonder if there is a way for this checkbox to be updated each time one of the sub panels list is changed, knowing that they all share the same model.

What do you think of it ?

NB : I saw this discussion http://www.nabble.com/Updating-distant-(unrelated)-components-via-Ajax-when-a-shared-model-changes-to13165777.html#a13165777 but I'm not sure it's the only way...

Let's see if Wicket surprises me one more time ;)

Hi

Thanks again !

Were you thinking of this discussion : http://www.nabble.com/AJAX-validation-and-multiple-requests-td15546309.html ?

If so it looks like there is no "real" feature for this need in the framework and that it should be done "by hand" each time, do we agree ?

Maybe this one

  http://www.nabble.com/generics-td18083910i60.html#a18347087

but it's a good idea to browse other messages on the list
about the ajax updates, there are several different ways
that people have come up with.

Best wishes,
Timo
