DeferredSessionStorageHandler race condition?

We are having an issue in our application whereby we have a
request
filter that calls PageFlowUtils.getCurrentPageFlow(
HttpServletRequest
request, ServletContext servletContext ).  Sometimes(but not
always)
this is returning null even though the filter is running for
the request
after the begin() method is called on our Controller. 
Here's the
sequence of events:
1) Controller's begin() method is called
2) begin() forwards to another action with redirect = true
3) request filter fires
 
Now, at the point the request filter fires for the request
corresponding
to the next action the DeferredSessionStorageHandler may not
have yet
applied its changes so _netui:curPageFlow isn't yet
committed to the
session and this causes PageFlowUtils.getCurrentPageFlow to
return null.
This usually only happens the first time I try to run the
flow.  Even if
I close my browser and make sure I get a new session, the
following
attempts all seem to work just fine.  I'm not sure what it
is about the
first run that seems to make things fail.  Here's the
relevant log

Should I log a bug, or am I doing something wrong?  I
haven't yet tried
to create a simple test case.  I'm on WebLogic 9.2 MP1, BTW.
 If it is a
bug, is there any suggested work around?  I'd like/need to
keep my
redirect = true.  Thanks,
Micah
