Could not obtain command object from portlet session

[Josef Krupicka]

Hi,

i am trying Spring portlet MVC (version 2rc4) on small portlet. I have simple controller for custom config mode. SessionForm property is set to true. It works fine but when i logout and then login it doesn't work and writes this exception:
