Jason,
That older AMX code is all going away as soon as Anissa finishes the
conversion to the new AMX.v3 code; it is definitely not an issue with
the AMX.v3 code.
Is there a way I can reproduce this simply, say with CLI? I'm not
seeing the page in the GUI. Maybe an XML snippet would be all I need
to see this problem.
