Why the Ajax round-trips for each "keyup" to extract the model's object?
Have you tried to implement just the Save link/button and then look-up the
model object from inside the onClick() method?
In your case it would come from the PropertyModel you use already:
TextField description = new TextField("description",new
PropertyModel[Meeting](meeting, "description"))
change to:
IModel descriptionModel = new
PropertyModel[Meeting](meeting, "description"));
TextField descriptionTextField = new TextField("description",
descriptionModel );
and your link becomes:
private class LinkSave(id: String, meeting: Meeting) extends
AjaxLink[String](id) {
@SpringBean
var meetingMediator: TMeetingMediator = _
def onClick(target: AjaxRequestTarget) {
meetingDAO.saveMeeting(descriptionModel.getObject())
}
}
Unless you want to also update some other element on the screen with each
user key press I really don't think you need the "keyup" listener.
