Thank you both for your feedback, everything is in place now.
For the record, the code that generates the required javascript now is:
"$('#" + markupId + "').on('blur', '.df', function() {var comp =
$(this).attr('name'); var cid=$(this).attr('id'); var data = {};
data['component']=comp; Wicket.Ajax.post({'u':'" + callbackUrl + "',
'e':'blur', 'c':cid, 'ep': data});});
Passing the component id to Wicket.Ajax.post automatically adds its current
value to the post parameters. So I only had to use 'ep' to pass the
component's name so that AbstractDefaultAjaxBehavior#respond() can know
which component to update.
