jBPM customization and custom workflow deployment

Aaaaahhhhh…  :(

Hello, guys and girls.
Please, help me with this issue.

I have a workflow that deploys correctly and works fine. BUT.
I need to use mail nodes and mail actions that come up with jPLD 3.2.
So.
I modified my processdefinition.xml to correspond jPDL 3.2 version as shown below:

<process-definition xmlns="urn:jbpm.org:jpdl-3.2" name="scwf:publishwhitepaper">

and added mail action to one of events:



<mail name="mailtest" to="#{notificationRecipient}">
  <subject>Hello, #{notificationRecipient}</subject>
  <text>Dear #{notificationRecipient}, please, do not reply to this message.</text>
</mail>


This is just a test…
Okay, now because jBPM engine will send e-mails, I need to setup SMTP rules.

I looked into XMLs in ../WEB-INF/classes/alfresco folder and found that workflow-context.xml contains the following:


<!–                     –>
<!– jBPM Implementation –>
<!–                     –>

<bean id="jbpm_configuration" class="org.alfresco.repo.workflow.jbpm.AlfrescoJbpmConfigurationFactoryBean">
    <property name="sessionFactory" ref="sessionFactory"/>
    <property name="configuration" value="classpath:org/alfresco/repo/workflow/jbpm/jbpm.cfg.xml"/>
</bean>

Well, I created package ../WEB-INF/classes/org/alfresco/repo/workflow/jbpm and put jbpm.cfg.xml into this folder. It contains only the following:

<jbpm-configuration>
  <string name="jbpm.mail.smtp.host" value="localhost" />
  <string name="jbpm.mail.port" value="9025" />
</jbpm-configuration>

Well, everything looks great and I'm starting Alfresco…

And have this:

How changing version from 3.1 to 3.2 may cause this:
instance not of expected entity type: org.jbpm.graph.node.Join is not a: org.jbpm.graph.def.Node   ???


What I done wrong? What should I do to make this working?
Please, help ASAP.

Thank you very much!
