    Remoting and java map to js map error conversion

    Filippo Newbie

      Hi,
      I found an error on interface produced by Seam remoting on JAVA MAP which is converted to BAG type.

      Here is an example of what is produced by Seam:
      Seam.Remoting.type.parent.__metadata = [
      {field: "name", type: "str"},
      {field: "children", type: "bag"}];

      Javascript model downloaded from server correctly contains MAP type.
      If I manually change in the interface 'bag' with 'map' all goes well.
      I use the CVS SEAM updated version.

      Anyone noted that?

      thanks

          Fixed in CVS, sorry about that.

            I thank you very much!

            Now I get an error using the latest cvs version.
            In fact I get a ClassNotFoundException on org.jboss.seam.core.Hibernate.
            Looking for that on Fisheye shows that this class was deleted 3 days ago.
            Could you suggest how to modify my components.xml in order to work with latest cvs version?

            My actually configuration is

            <components>
            
             <component name="org.jboss.seam.core.init">
             <property name="myFacesLifecycleBug">false</property>
             <property name="debug">true</property>
             </component>
            
             <!-- 120 second conversation timeout -->
             <component name="org.jboss.seam.core.manager">
             <property name="conversationTimeout">120000</property>
             </component>
            
             <!-- Bootstrap Hibernate -->
             <component name="cbiFeDatabase"
             class="org.jboss.seam.core.ManagedHibernateSession"/>
             <component class="org.jboss.seam.core.Hibernate" installed="true"/>
             <component class="org.jboss.seam.core.Microcontainer"
             installed="true"/>
            
             <component class="org.jboss.seam.core.Ejb" installed="false"/>
            
            </components>





            the stack trace is

              <component name="sessionFactory" class="org.jboss.seam.core.HibernateSessionFactory"/>


              It is in the docs :-)

                Thanks Gavin.

                Sadly I get the following exception on the first call (webapp is deployed without errors):
                org.hibernate.SessionException: Session is closed!

                Code is the same, hibernate.cfg.xml is the same too, components.xml is

                <components>
                
                 <component name="org.jboss.seam.core.init">
                 <property name="myFacesLifecycleBug">false</property>
                 <property name="debug">true</property>
                 </component>

                 <component name="sessionFactory"
                 class="org.jboss.seam.core.HibernateSessionFactory" />
                 <component name="cbiFeDatabase"
                 class="org.jboss.seam.core.ManagedHibernateSession">
                 <property name="sessionFactoryJndiName">java:/cbiFeDatabase</property>
                 </component>
                
                 <component class="org.jboss.seam.core.Microcontainer"
                 installed="true" />
                
                 <component class="org.jboss.seam.core.Ejb" installed="false" />
                
                </components>
                
                


                as suggested by docs.

                Thanks in advance.


                By the way, I'm very impressed by the dynamic generation of docs from xml. It's the first time I've generated the docs and I think it's very powerful.

                  This seems to be a Jetty-specific problem. Why does Jetty call equals() after a Session.setAttribute() ? Is this how it does dirty checking?

                  Yew!

                  Well, add an issue to JIRA.

                    I reproduced the problem (very tricky) integrating 'Hibernate' example and posted to jira the 6 relative new/updated files.

                    thanks
