valueChangeListener on h:selectOneMenu not working
We are in the process of upgrading our application from richFaces 3.3.2 and MyFaces 1.2 to richFaces 4.2.2.Final and MyFaces 2.0. I am having issues to get valueChangeListener to execute on a picklist. I followed the example on RichFaces showcase but still not able to get it to work. Here is the code:

Here are the libraries I am using:
richfaces-components-api-4.2.2.Final.jar
richfaces-components-ui-4.2.2.Final.jar
richfaces-core-api-4.2.2.Final.jar
richfaces-core-impl-4.2.2.Final.jar
myfaces-api-2.0.0.jar
myfaces-impl-2.0.0.jar
I would appreciate anyone providing me some direction on where I am going wrong.
Thanks,
