Primefaces fileUploadListener is not invoked

Primefaces fileUploadListener is not invoked

I'm using,
GlassFish 4.0
JSF 2.0
Primefaces 3.5
I have this fileUpload component on an XHTML page.
<h:form enctype="multipart/form-data">
<p:fileUpload id="txtCatImage"
value="#{testManagedBean.uploadedFile}"
mode="advanced"
sizeLimit="100000"
multiple="false"
showButtons="true" allowTypes="/(\.|\/)(gif|jpe?g|png)$/"
fileUploadListener="#{testManagedBean.fileUploadListener}"/>
<p:message for="txtCatImage" showSummary="false"/>
<p:commandButton id="btnSubmit"
actionListener="#{testManagedBean.insert}"
icon="ui-icon-check" value="Save"/>
</h:form>
This is the corresponding managed bean.
@ManagedBean
@ViewScoped
public final class TestManagedBean implements Serializable
{
private static final long serialVersionUID = 1L;
private UploadedFile uploadedFile;
public TestManagedBean(){}
public UploadedFile getUploadedFile() {
return uploadedFile;
}
public void setUploadedFile(UploadedFile uploadedFile) {
this.uploadedFile = uploadedFile;
}
public void fileUploadListener(FileUploadEvent event)
{
uploadedFile=event.getFile();
System.out.println("fileUploadListener invoked.");
}
public void insert()
{
if(uploadedFile!=null)
{
System.out.println(uploadedFile.getFileName());
}
else
{
System.out.println("The file object is null.");
}
}
}
The file upload listener as mentioned - fileUploadListener() is never
invoked.
The file upload filter is mapped in web.xml as follows.

I have added Apache-commons-fileupload and Apache-commons-io to the
classpath. The same thing works in my earlier project with Spring/JSF.
I can't see what I'm missing here. Does it have to do something with the
version of the server?
