    @In(create = true) @Out works fine in 1.1.5.GA and not in 1.

      1.1.5.GA
      Seam creates one instance of userDomain and for each method call
      Seam injects the same instance of userDomain.

      1.2.0.PATCH1
      For each method call Seam creates a new instance of userDomain.

      Can anybody here tell me what's going on?

      Thanks,
      /Kenneth

          Any help.... please :-)

          It's a really big problem for me, that Seam 1.2.0 creates a new instance of userDomain when an AccountBean method is invoked - for each AccountBean method call I get a new userDomain instance !

          Seam 1.1.5 creates one instance of userDomain and use this instance when an AccountBean method is invoked - for each AccountBean method call I get the same userDomain instance (this is the expected behaviour).

          Because of this I can't use Seam 1.2.0 for my application :-(

            What is "userDomain"? (StatefullBean, StatelessBean,...)
            and what scope is it in? Use debug.seam to check if it is really there where you want it.

            I`ll check the @In (create=true) acting today when I come to coding but I`ve moved to 1.2PATCH1 from 1.1.5 and don`t have this problems.

              userDomain is an instance name for an EntityBean (User) and AccountBean is a StatefulBean with the scope CONVERSATION.

              I have debugged the code and can see that every time Seam 1.2.0 invokes a method on AccountBean a new instance of userDomain (User) is created and injected.
              But in Seam 1.1.5 only one userDomain (User) instance is created and this instance will be injected in every method call on AccountBean.

              I will try to debug some more and test it against Seam 1.1.6.

                No comments/help from the people behind JBoss Seam?

                It's really strange, because I only replaced the 1.1.5 jar files (jboss-seam.jar and jboss-seam-ui.jar) with the 1.2.0 files.

                Have something changed in the @In @Out behaviour in 1.2.0 or/and in the bijection implementation?

                  Nothing significant has changed, no.

                  No-one can help you if you havn't showed the code for UserDomain.

                      The behaviour for pages.xml have changed in 1.2.0 ! Because if I remove pages.xml everything will work out just fine.

                      pages.xml:

                      <!DOCTYPE pages PUBLIC "-//JBoss/Seam Pages Configuration DTD 1.1//EN" "http://jboss.com/products/seam/pages-1.1.dtd">
                      
                      <pages>
                       <page view-id="/xhtml/account/create/agreement.jspx" action="#{accountBean.begin}"/>
                       <page view-id="/xhtml/account/create/create.jspx" action="#{accountBean.validatePageRequest}"/>
                       <page view-id="/xhtml/account/create/welcome.jspx" action="#{accountBean.validatePageRequest}"/>
                      </pages>
                      


                      Something in pages.xml triggers the above problem (for each method call Seam creates a new instance of userDomain).

                        Just loud thinking:

                        you always get a new (not nested) conversation with seam 1.2PATCH1 and then @In can`t inject the old instance? And this is not so when you move back to 1.1.5, for some reason...

                        Also, I don`t understand why do you return a String from #{acountBean.begin}? That makes things somewhat overcomplicated to me.

                          you always get a new (not nested) conversation with seam 1.2PATCH1 and then @In can`t inject the old instance? And this is not so when you move back to 1.1.5, for some reason...


                          With 1.2.0 and pages.xml I get a new conversation id at each request for the current conversation and that's not correct because @In can`t inject the old instance, but for 1.1.5 and pages.xml I have the same conversation id throughout the conversation.

                          Because my conversation consist of 3 pages (request).

                          Page 1) Disclaimer - accept yes or no (Conversation Begin)

                          Page 2) User enter personal data

                          Page 3) Welcome text

                          If a new user try to hit page 2 or page 3 without accepting the "Disclaimer" at page 1, then the conversation will end.

                          I return a String in #{acountBean.begin} to navigate to the right 'Begin' page (I'm using JSF navigation).

                          Maybe it's the wrong way to use Seam and page actions (from 1.2.0) but as I have mentioned earlier everything works just fine for 1.1.5 :-)

                            Now it works :-)

                            Old pages.xml (OK for 1.1.5 and not OK for 1.2.0):

                            <!DOCTYPE pages PUBLIC "-//JBoss/Seam Pages Configuration DTD 1.1//EN" "http://jboss.com/products/seam/pages-1.1.dtd">
                            
                            <pages>
                             <page view-id="/xhtml/account/create/agreement.jspx" action="#{accountBean.begin}"/>
                             <page view-id="/xhtml/account/create/create.jspx" action="#{accountBean.validatePageRequest}"/>
                             <page view-id="/xhtml/account/create/welcome.jspx" action="#{accountBean.validatePageRequest}"/>
                            </pages>
                            


                            New pages.xml (OK for 1.2.0. Havn't tried it for 1.1.5):

                            <!DOCTYPE pages PUBLIC "-//JBoss/Seam Pages Configuration DTD 1.1//EN" "http://jboss.com/products/seam/pages-1.1.dtd">
                            
                            <pages>
                             <page view-id="/xhtml/account/create/create.jspx" action="#{accountBean.validatePageRequest}"/>
                             <page view-id="/xhtml/account/create/welcome.jspx" action="#{accountBean.validatePageRequest}"/>
                            </pages>
                            


                            For 1.2.0

                             <page view-id="/xhtml/account/create/agreement.jspx" action="#{accountBean.begin}"/>
                            


                            triggers a new conversation id for each request in the same conversation.

                            As mentioned earlier maybe it's not the correct way I have used page actions, but it's difficult to know, because it works just fine for 1.1.5 and not for 1.2.0 - maybe it have been a bug for Seam versions <1.1.5 (1.1.6) and the bug have been fixed for 1.2.0 or this is a new bug in 1.2.0?

                              I cannot reproduce this behavior. If a page action begins a conversation, everything works just fine for me.

                                What can I say? Very odd :-)

                                But now it works fine for me and it also works fine for you, so everybody are happy :-)

                                Thanks for your time and help.
