Step 11 of webcenter tutorial portlets Interaction is not working

Question

I completed the tutorial. Everything worked except for the interaction between the portlets. When I click on Show Details on the Products portlets nothing changes in the Product Information portlet!?
I reviewed and validated that all steps were done as described but couldn't get the interaction to work.
1. Ran MyTutorialPortlets view.jsp page and data was displayed correctly.
2.The webcenter MyPage.jspx shows both portlets with data displayed correctly on initial display. And the partialTriggers on second portlet references the id of the first portlet (no colons were used)
3. MyTutorialPortlet's oracle-portlet.xml has the productID as a parameter
Here is the all the relevent code that will help in identifying the error:
MyTutorialPortlet's oracle-portlet.xml seems correct:
<portlet-app-extension xmlns="http://xmlns.oracle.com/portlet/oracle-portlet-app">
<portlet-extension>
<portlet-name>Products</portlet-name>
<navigation-parameters>

Please see if you can provide a solution.

Answer 1

Here is the code.
// Form field names
public static final String PARAMETER1 = "productId";
public static final String FORM_PARAMETER1 = "form_Parameter1";
public static final String FORM_SUBMIT = "dosub";
// Portlet Modes
public static final String MODE_NAME_PARAM = "mode";
public static final String MODE_VIEW = "view";
public void processAction(ActionRequest request,
ActionResponse response) throws PortletException,
IOException {
// Determine what kind of action we have by examining the mode parameter
boolean viewMode =
MODE_VIEW.equals(request.getParameter(MODE_NAME_PARAM));
// Extract the form field parameter and pass it through as a portlet parameter
String param1 = request.getParameter(FORM_PARAMETER1);
if (param1 == null) {
param1 = ProductsBean.DEFAULT_PRODUCT_ID;
if (viewMode) {
// Set the new parameter values. These will be intepreted by the
// container as navigational parameters as the names match the names of
// the declared parameters.
response.setRenderParameter(PARAMETER1, param1);
} else {
// Determine which action.
String okAction = request.getParameter(OK_ACTION);
String applyAction = request.getParameter(APPLY_ACTION);
if (okAction != null || applyAction != null) {
// Save the preferences.
PortletPreferences prefs = request.getPreferences();
String param = request.getParameter(PORTLETTITLE_KEY);
prefs.setValues(PORTLETTITLE_KEY, buildValueArray(param));
prefs.store();
if (okAction != null) {
response.setPortletMode(PortletMode.VIEW);
response.setWindowState(WindowState.NORMAL);
