Hi Ed,

Do you think this will be fixed in 2.2? I'm seeing more complaints about it.

I can commit to making sure it works for the new javax.faces.flow.ViewScoped managed beans, which is based on CDI.

I will also investigate what it will take to make it work for the non-CDI based ones as well.

Thanks for bringing my attention to it.

This one is proving very tricky due to the many points in time and different scenarios where sessions can be invalidated. The fix for this must be very closely scrutinized, and, more importantly, must pass all the automated tests.

We're also getting reports of memory leaks with view-scoped beans. I've verified the leak, but not traced its exact cause. I'm assuming that the leak is related to this issue.

Any opinion on that or insight into how the instances are referenced? I'm assuming that if view-scoped beans aren't eligible for GC when the session ends then they must be tied to application scope or to a ThreadLocal. Any other possibilities?
