AbstractWizardFormController and VelocityViewResolver

[darfed]

Spring 2.0.4 - I am implementing AbstractWizardFormController to handle a two page form. I am running into an issue that appears to be caused by the (in this case) VelocityViewResolver settings

   <property name="exposeRequestAttributes">
      <value>true</value>
    </property>
    <property name="exposeSessionAttributes">
      <value>false</value>
    </property>

The error I am finding in the application log is after formBackingObject is executed at the time the request and session attributes are added to the model. At that time in the following exception is thrown -

javax.servlet.ServletException: Cannot expose session attribute 'com.virginmedia.sfweb.controller.impl.CreditCheck FormControllerImpl.PAGE.creditCheckFormBean' because of an existing model object of the same name

	

javax.servlet.ServletException: Cannot expose session attribute 'com.virginmedia.sfweb.controller.impl.CreditCheckFormControllerImpl.PAGE.creditCheckFormBean' because of an existing model object of the same name
org.springframework.web.servlet.view.AbstractTemplateView.renderMergedOutputModel(AbstractTemplateView.java:154)
org.springframework.web.servlet.view.AbstractView.render(AbstractView.java:247)
org.springframework.web.servlet.DispatcherServlet.render(DispatcherServlet.java:1123)

Has anyone run into similar issues? I am straitened by the fact that I am adding locally to an already sizeable codebase and cannot safely change the two properties referenced above (which I am not fond of at all - rather like providing the front end with a vast bucket of data and asking it to help itself) without running the risk of breaking the application elsewhere. This is a codebase that is maintained elsewhere.

I posted incorrect settings for the exposeSessionAttributes params this should have read

    <property name="exposeRequestAttributes">
      <value>true</value>
    </property>
    <property name="exposeSessionAttributes">
      <value>true</value>
    </property>
