Is your issue the same as RF-14010? There are currently no plans to resolve that one. Otherwise, file a new issue.
We see a similar problem as the OP and I think it is not the same as RF-14010
I just created [RF-14026] for this issue and included a small Maven app demonstrating the problem.
My problem is with expanded=false, not the same of duplicating ids of RF-14010. It is the same problem of RF-14026, and it is a problem not just with switchType=client, but also server and ajax, like I said before in the thread.
