Our developer has confirm this is a bug: When a response filter is used for
a request, the ability to reconstruct individual pieces of the response
buffers on subsequent requests will be lost. As a result the substitution
block that goes into the response buffers is no longer available as a
discrete item for us to act on.
However, this bug won't be fixed unless there is a specific customer
scenario that they were trying to solve. Therefore, I think the best way to
get a hot fix for this issue to submit a support service request to our
PSS. Please refer to
http://msdn.microsoft.com/subscriptions/phone/ for how
to submit technical support incidents.
Hope this can help you get the problem resolved.
