Spring Portlet MVC and Session Problem

[dowser]

Hello,

we convert our current application from spring mvc to pring portlet mvc. everthing works fine, but a small error occurs. this error causes that the application redirects to an error view.

The formBackingObject set a command object to the form.
The web form calls a SimpleFormController and is bind with a validator.
On Submit the validator is called an then the onBindandValidate Method.
Then an warning comes up (no errors are set in the validator).

- What does this warning mean?
