[Seaside] Execute jQuery script upon #onAjaxComplete?

[Esteban A. Maringolo]

Try this:

html document addLoadScript: (
  html jQuery document onAjaxComplete: (
    (html jQuery id: self  systemMessageNotifier mainDivId)
       load
         global: false; "to avoid infinite recursion see [1]"
         html: [:r | self systemMessageNotifier renderContentOn: r ]
     )
).

[1] If $.ajax() or $.ajaxSetup() is called with the global option set
to false, the .ajaxComplete() method will not fire.
