MyFaces 1.2.6 immediate attribute on command button - required validation

All,

  I have been using the immediate attribute on all my cancel command buttons since MyFaces 1.1 and have had no issues with its usage. I am attempting to upgrade to Myfaces 1.2.6 and suddenly all my cancel command buttons do not work as intended. This is the behavior that I notice.
1) All required validations of fields fire the moment I click the "immediate" tagged btn.
2) The listener for the cancel btn is never reached.

I cannot be missing anything in the basic usage itself because this was working perfectly before the upgrade. So what else could I be missing ? Or is this a bug in this version ? Some clarity on this from the gurus would be appreciated.

FYI I have already read the wiki on using the immediate attribute at apache.org and I am using the same techniques mentioned there

Ciao
