Created by: Farhang Farid on 20-12-2009 10:17:04 PM Hello Everyone I have come across what I think is a major CVP bug and I want to confirm this with everyone. When I use getAllSessionData in a custom element to retrieve a Hashmap of all variables in the session I see a strange behavious: If I have two concurrent calls running on the same application at the same time , the Hashmap that is returned from getAllSessionData contains variables set/used by both applications. According to the CVP documentation getAllSessionData should only return the session variables that are stored in the session of "the call" up to that point, but this clearly not happening I have ran many test and I am convinced that this is an issue in CVP code. Here is an example of tests that I have ran so far : On my application I retrieve the session ID and store it in the session. when I use getAllSessionData in the application and print out all session variables I can see the session ID from both calls stored in the session. Any ideas?

As for your issue, I believe it has got to do with the scoping of the Hashmap variable you are using in the application. Mind you, there will be only one instance of the custom element class that exists on the JVM. The same instance is used to handle concurrent multiple calls, and hence if you have your hashmap defined as a class variable, there is a high chance that there is data corruption between calls. To avoid this problem, make sure you read and write the hashmap variable outof/into the sessionData only in local scope (within the method). This single instance philosophy is documented in the Programmers Guide. I strongly suggest that you track back the read/writes of the hashmap in your callflow, this could solve your issue. Hope this helps, Ranjana.

When I use System.out.println to display the result of getAllSessionData while I have 2 concurrent calls, each shows only the Session Data for that phone call.
