Ok. will do it.
Do you know the issue number for the one you mentioned before? I'll put references to it in the new issue.

There were a couple problems found in Admin GUI and CLI relating to Load Balancer, and the root cause is in AMX code.
The bug# is 6569828 and  6569165.   Lloyd has marked the bug fixed in build 51.  I also tested that and  no longer see the NPE.
You can take a look at these 2 bugs.

thanks
Anissa
