I have added several filters in the VSM in the listener step (first step) .. all my filters are xml xpath filter which is used to fetch the value from the request being sent from client to VSE..
So the filter in step is "lisa.vse.http.current.transaction.body"
My issues is all my filters are working , except one filter, which is no different compare to other filter but still fails..
The test events log shows this message..
The property value was empty, the property key was ' lisa.vse.http.current.transaction.body'
I am not sure why this says empty only for this filter.. any thoughts please ?
