    How to use Conversation in Seam 3...

    hantsy bai Master

      I used a Conversation scoped bean to process add/edit action...The problem is


      1. If validation failed, the input values are missing(restored to the default, add is empty and 'edit' is the unchanged), in the Seam 2 application, all like these worked well.
      Where is wrong


      2. I used Richfaces 4.0.0.Final, and I wanted to use a popupPanel to update the some content(added some areacode in the cityEdit page), the field values in the popupPanel were not updated.


      3. When the validation was failed in the popupPanel, it did not stop to close popupPanel(closed the popupPanel)...and when I opened the popupPanel again, it highlight the field label and input field...why the validation was delayed...

          Any help is appreciated.

          • 2. Re: How to use Conversation in Seam 3...
            hantsy bai Master

            I really do not understand the Seam 3 converstation(3.1.0.Beta2)... I modified the PortEditAction code(in fact I copied the code form Seam Booking)...


            @Stateful
            @ConversationScoped
            @Named("portEdit")
            public class PortEditAction {
            
                 @PersistenceContext(type = PersistenceContextType.EXTENDED)

                 public void setCurrentPort(Port currentPort) {
                      this.currentPort = currentPort;
                 }
            
                 // @Begin()
                 public void initAdd() {

              Shane Bryzak Master

              Where are the @Begin and @End annotations that you're using in your code coming from?  It seems like you're not promoting your conversation to long-running, you need to inject the Conversation object like so:




              @Inject Conversation conversation;





              Once you do that, you can call conversation.begin() and conversation.end() at the places where you want to begin and end the conversation.

                I should add, that just in case you're using the new conversation annotations from the Seam Faces module (the ones that haven't even been released or documented yet), then you probably haven't enabled ConversationBoundaryInterceptor in your beans.xml.

                    it seems use the manual way is more stable...I removed the Extened type attribute on the @PersistenceContext


                    but the three problems are still there...


                    1. If validation failed, the input values are missing(restored to the default, add is empty and 'edit' is the unchanged one), in the Seam 2 application, all like these worked well. Where was wrong?
                    
                    2. I used Richfaces 4.0.0.Final, and I wanted to use a popupPanel to update the some content(added some areacode in the cityEdit page), the field values in the popupPanel were not updated(empty string in the areaCode in the example).
                    
                    3. When the validation was failed in the popupPanel, it did not stop to close popupPanel(closed the popupPanel)...and when I opened the popupPanel again, it highlight the field label and input field...why the validation was delayed...
