Train model process - How to reset its max path

Question

Hi everyone,
Could someone please point me into any document or give me any advice on how I can clear the max path of the process train. The process train that I created is called every time by the registration user who enters many applications. Each application creates a process train with the 8 pages they need to go through. The first time it works perfectly, but the second time, because they finished the first process, the component still thinks that they already went through all the pages and allows them to click the last page. I noticed the class is based on a session bean so I suppose somewhere I need to call clearMaxPath() from class ProcessMenuModel. I have been trying to create a method in the main class but it seems I cannot access this method. Any ideas would be appreciated. The class where I was trying to add this method is below:
package esolve.userinterface.menu;
import java.beans.IntrospectionException;
import java.io.Serializable;
import oracle.adf.view.faces.model.MenuModel;
import oracle.adf.view.faces.model.ProcessMenuModel;
public class ProcessTrainModelAdapter implements Serializable {
private String _propertyName = null;
private Object _instance = null;
private transient MenuModel _model = null;
private Object _maxPathKey = null;
public MenuModel getModel() throws IntrospectionException {
if (_model == null)
_model = new ProcessMenuModel(getInstance(),
getViewIdProperty(),
getMaxPathKey());
return _model;
public String getViewIdProperty() {
return _propertyName;
* Sets the property to use to get at view id
* @param propertyName
public void setViewIdProperty(String propertyName) {
_propertyName = propertyName;
_model = null;
public Object getInstance() {
return _instance;
* Sets the treeModel
* @param instance must be something that can be converted into a TreeModel
public void setInstance(Object instance) {
_instance = instance;
_model = null;
public Object getMaxPathKey()
return _maxPathKey;
public void setMaxPathKey(Object maxPathKey)
_maxPathKey = maxPathKey;
And from the faces config this is the session bean
<!--Step 4. create the train menu model -->
<managed-bean>
<managed-bean-name>createTrainMenuModel</managed-bean-name>
<managed-bean-class>esolve.userinterface.menu.ProcessTrainModelAdapter</managed-bean-class>
<managed-bean-scope>session</managed-bean-scope>
<managed-property>
<property-name>maxPathKey</property-name>
<value>8</value>
</managed-property>
<managed-property>
<property-name>viewIdProperty</property-name>
<value>viewId</value>
</managed-property>
<managed-property>
<property-name>instance</property-name>
<value>#{createTrainNodes}</value>
</managed-property>
</managed-bean>

Hi Dennis,
Please see example code. In here it works well because of the change of data source. If you use a .json file rather than json object as data source ( I don't know how to do it in JSBin), bugs appear as I mentioned above.
Here's a simple test case using .json file as data source, hope it helps to make me understood:
Step1. select "item 0" , and check "mcb0_0" & "mcb0_1".
Step2. select "item 1". See what happens.
Result:
1."mcb1_0" & "mcb1_1" are automatically selected.------- WRONG.
2. The value of MultiComboBox is mcb0_0mcb0_1.--------WRONG.
