Help with Updating a Session Entity Object

[clerum]

OK-

In my application when a user logins in I outject an user Session object named authuser. This is the object I use to pull the logged in users organization, name, etc..This seems to work fine.

I have new page which allows the user to edit their information.

<h:form id="updateUserForm"> 
 
        <rich:panel> 
            <f:facet name="header">Edit Profile</f:facet> 
            <s:decorate id="usernameDecoration" template="/layout/edit.xhtml"> 
                <ui:define name="label">Email Address</ui:define> 
                <h:inputText id="username" required="true" value="#{authuser.username}"/>                 
            </s:decorate>
            <s:decorate id="firstnameDecoration" template="/layout/edit.xhtml"> 
                <ui:define name="label">First Name</ui:define> 
                <h:inputText id="firstname" required="true" value="#{authuser.firstname}"/>                 
            </s:decorate>
            <s:decorate id="lastnameDecoration" template="/layout/edit.xhtml"> 
                <ui:define name="label">Last Name</ui:define> 
                <h:inputText id="lastname" required="true" value="#{authuser.lastname}"/>                 
            </s:decorate>
            <s:decorate id="organizationDecoration" template="/layout/edit.xhtml"> 
                <ui:define name="label">Organization</ui:define> 
                <h:outputText id="organization" required="true" value="#{authuser.organization.name}"/>                 
            </s:decorate>
            <div style="clear:both"/>            
        </rich:panel> 
 
          <div class="actionButtons">
            <h:commandButton id="update" value="Update" action="#{userutil.updateUser(authuser)}"/>
            <h:commandButton id="cancel" value="Cancel" action="/home.xhtml"/>            
             </div>
        
    </h:form> 

public void updateUser(User selectedUser)
     {
          user = em.merge(selectedUser);
          em.persist(user);
        }

This all appears to work however if the user tries to edit their information again then get an error about that row already being edited by another user. I can see from the debug page that the version differs between the database and the Session object authuser.

How do I go about updating the authuser session bean?

Is there a correct way to handle situations like this which would have the bean updated automatically?

Bump.

I'm not sure about that, but I would try outjecting the authUser in your userUtil component. Otherwise, at least in my understanding, your authUser component isn't updated.

I found my problem to be what looks to be rather common. I was outjecting an entity bean and then trying to work with it later on.

I stuffed that entity into a SFSB and gave it an extended persistance context.

Then I just have a simple save method which calls an em.flush()
