Edson Tirelli resolved JBRULES-3052.
------------------------------------
Resolution: Done
As discussed over the IRC, this is fixed now. The traditional "from accumulate"
syntax supports only a single accumulate function. The top level accumulate CE supports
multiple functions.

------------------------------------
Still occurs with upstream HEAD compiled at 27-May-2011 10:00 UTC, for instance:
rule "ocount"
when
accumulate( Object(), $c: count(1) )

Always good to have you around Wolfgang! :)
There was a bug when using the top level accumulate CE with a single function. Fixed now.
