Hi Paul, thanks very much for your help! I followed your suggestion but this peace of code doesn't compile unfortunately:
IModel descriptionModel = new PropertyModel[Meeting](meeting, "description")); I have tried val descriptionModel[IModel] = new PropertyModel[Meeting](meeting, "description")); //wrong systax for scala and val descriptionModel = new IModel[Meeting](meeting, "description")); // IModel can't be instanced But I'm doing this thing wrong. I made a great progress with my app but now I'm struggling with this issue and I spent a lot of time to archive this simple task. If I'm doing this stuff with java my life could be much easier :-D. I'll appreciate your hep again Thanks very much Bera 2013/5/10 Paul Bors <p...@bors.ws> > 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. > > ~ Thank you, > Paul Bors > > > On Thu, May 9, 2013 at 11:03 PM, Bruno Moura <brunormo...@gmail.com> > wrote: > > > I'm trying to implement a ListView and in on column of it I added a > > listView, for each line, > > I want to save the data inserted on it and update the model: > > > > I'm implemented the code bellow: > > > > val description = new TextField("description",new > > PropertyModel[Meeting](meeting, "description")) > > description.add(new AjaxFormComponentUpdatingBehavior("keyup") { > > protected def onUpdate(target: AjaxRequestTarget) { > > description.getDefaultModelObjectAsString > > } > > }) > > > > item.add(description) > > > > And I added a link for each line of my ListView for save the information > in > > database, > > each line is a instance of a model meeting as is showed bellow: > > > > item.add(new LinkSave("save", meeting)) > > > > private class LinkSave(id: String, meeting: Meeting) extends > > AjaxLink[String](id) { > > > > @SpringBean > > var meetingMediator: TMeetingMediator = _ > > > > setVisible(clickavel.asInstanceOf[Boolean]) > > add(new Label("label", new Model[String]() { > > override def getObject: String = "Save" > > })) > > > > def onClick(target: AjaxRequestTarget) { > > meetingDAO.saveMeeting(meeting) > > > > } > > } > > > > > > But unfortunately the code above doesn't work.
