Re: [flexcoders] Flex2/ColdFusion connectivity : session scope problem

I hope someone is actually looking into this. Here's a log of the null pointer exception when trying to use J2EE sessions. It's not terribly useful as the stack trace is not shown, but it does show that the exception occurred when trying to access the ColdFusion service, most likely the adapter class, coldfusion.flash.messaging.ColdFusionAdapter.

Any news on this issue from the Mystic ColdFusion Updater team?

This is a huge bug for us, since we'll need this to implement server-side security for each session on our project...

Objet : [flexcoders] Flex2/ColdFusion connectivity : session scope problem

I'm currently trying to use the ColdFusion session scope in my CFC-based services.

I've added some logging to check the #session.sessionId# and the onSessionStart/onSessionEnd event in my Application.cfc.

Problem :

- when using ColdFusion default sessions, a new session is started at each of my remoteObject calls,

- when using J2EE sessions, it generates a null exception at each of my remoteObject calls.

Is it a bug or is there some configuration parameters to use the ColdFusion session scope?

Thanks.
