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
