Hi,
I need to override TaskNode with my custome Node to add type attribute to it.
I read on the forum that for this I need update jbpm.cfg.xml with

<string name="resource.node.types" value="com/jbpm/node/node.types.xml" />

I've moved node.types.xml to the location above and updated task node value

<node-type element="task-node" class="com.jbpm.node.MyNode" />

I've created MyNode.java and override execute() method, created MyNode.hbm.xml

<?xml version="1.0" encoding="UTF-8"?>

<!DOCTYPE hibernate-mapping PUBLIC
 "-//Hibernate/Hibernate Mapping DTD 3.0//EN"
 "http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd">

<hibernate-mapping default-access="field">
 <subclass name="com.jbpm.node.MyNode"
 discriminator-value="M" extends="org.jbpm.graph.node.TaskNode">
 <property name="type" column="TYPE_" />
 </subclass>
</hibernate-mapping>

and updated hibernate.cfg.xml with MyNode.hbm.xml
Adn deployed the application. But when running I'm still having TaskNode returned to me and not MyNode.
Will the described above solution work or I need to change jbpm source to add type attribute?
Thank you.
