adding default Action to Node

[marcs]

Hi,

I'm developing a workflow for datamining application. Therefore I need to create my own nodes. These own nodes are no fancy new nodes, they basically extend the jbpm node with a default action.

What I did so far:
- extended the GPD to work with my own nodes
- extended my own node from the jbpm node and adapted the constructor

Adding nodes in the GPD works! But XML is not generated right.

What I get:

<node name="node1">
 <action></action>
</node>

What I expect:

<node name="node1">
 <action class="MyAction"></action>
</node>

Properly there is something wrong with my code.

public class MyNode extends Node {

 public MyNode() {
 Action action = new Action();
 action.setAcceptPropagatedEvents("true");
 action.setAsync("false");
 action.setConfigType("field");
 ImageDescriptor imageDescriptor = ImageDescriptor.createFromFile(null,
 "/icons/full/obj16/action_enabled.gif");
 action.setIconDescriptor(imageDescriptor);
 action.setElementId("org.jbpm.gd.jpdl.action");
 action.setLabel("Action");
 action.setNamePrefix("action");
 SemanticElementFactory factory = new SemanticElementFactory(
 "org.jbpm.gd.jpdl.editor");
 action.setFactory(factory);

 setAction(action);

 firePropertyChange("action", null, action);
 firePropertyChange("expression", null, null);
 firePropertyChange("className", null, null);
 firePropertyChange("configInfo", "", null);
 firePropertyChange("configType", "field", "field");
 firePropertyChange("className", null, "");
 firePropertyChange("expression", null, null);
 firePropertyChange("className", null, "MyActionClass");
 }
...
}

Is it actually doable? What am I doing wrong?

Thanks,
Marc
