Actually, i had a closer look to AjaxFormLoop. Here the Javascript that
launches trigger the start for add row event :
ajaxFormLoop : function(spec)
{
var rowInjector = $(spec.rowInjector);
$(spec.addRowTriggers).each(function(triggerId)
{
$(triggerId).observe("click", function(event)
{
$(rowInjector).trigger();
Event.stop(event);
})
});
}
Maybe you can override this method to add an Ajax call (event link) before '
$(rowInjector).trigger();' to call a method that verify if the trigger
method must be called.
I'm not sure this is the easiest way :)
