[jboss-user] [JBoss Seam] - Re: cant figure out why my transaction is null : same code w

[wiggy]

okay can any one help on this.  

I've imported the same code base onto my pc at home - think i have the same config but it works fine 

at home i stall have the persistence.xml as 

  | <persistence xmlns="http://java.sun.com/xml/ns/persistence" 
  |              xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
  |              xsi:schemaLocation="http://java.sun.com/xml/ns/persistence http://java.sun.com/xml/ns/persistence/persistence_1_0.xsd" 
  |              version="1.0">
  |              
  |    <persistence-unit name="WillsSeamProject">
  |      <provider>org.hibernate.ejb.HibernatePersistence</provider>
  |       <jta-data-source>WillsSeamProjectDatasource</jta-data-source>
  |       <properties>
  |          <property name="hibernate.dialect" value="org.hibernate.dialect.MySQL5InnoDBDialect"/>
  |          <property name="hibernate.hbm2ddl.auto" value="create-drop"/>
  |          <property name="hibernate.show_sql" value="true"/>
  |          <property name="hibernate.format_sql" value="true"/>
  |          <property name="jboss.entity.manager.factory.jndi.name" value="java:/WillsSeamProjectEntityManagerFactory"/>
  |       </properties>
  |    </persistence-unit>
  | 

and the nodeHome java is - which is still a POJO component - 


  | 
  | @Name("nodeHome")
  | public class NodeHome extends EntityHome<Node>
  | {
  | 
  |     @RequestParameter 
  |     Long nodeId;
  | 
  |     @RequestParameter 
  |     String reasonForLink;
  | 
  |     @Factory("node")
  |     public Node initNode() {return getInstance();}
  |     
  |     @Override
  |     public Object getId() 
  |     { 
  |         if (nodeId==null)
  |         {
  |             return super.getId();
  |         }
  |         else
  |         {
  |             return nodeId;
  |         }
  |     }
  |     
  |     @Override @Begin
  |     public void create() {
  |         super.create();
  |     }
  |  	
  |     /*
  |      * action to link two nodes
  |      * 
  |      */
  |     public Link addLinkToNode (Node otherNode)
  |     {
  |     	Link newLink ;
  |     	
  |     	newLink = this.getInstance().addLinkTo(otherNode);
  |     	if (reasonForLink != null)
  |     	{
  |     		newLink.setDescription(reasonForLink);
  |     		newLink.setLastUpdated();
  |     	}
  |     	this.getInstance().setLastUpdated();
  |     	this.update();
  | 
  |     	return newLink;
  | 
  |     }
  | }
  | 

with .html client as

i'd swear i cant see the difference but the error code at work shows differently - has any one got a clue from the trace error on the first post as to what might be going on?
