<DIV><FONT face=Arial size=2>IConstraint is indeed used for storing the
constraint for each of the outgoing connections of an (X)OR split. This
constraint is currently represented as a String, but this does not mean it will
be interpreted at runtime. We are currently thinking about making these
conditions similar to the normal LHS of a rule, so you could say something like
when "Person(age > 20)" as constraint. These constraints will then be
evaluated the same way as the LHS of a rule. I'm pretty close to getting
(X)OR splits working, the tooling (eclipse) is still the hardest part
though.</FONT></DIV>

<DIV><FONT face=Arial size=2>The definition of variables for a ruleflow would
allow you to define variables local to one specific ruleflow (instance).
They are similar to globals but their scope is different: globals have one value
for an entire workingMemory, ruleflow variables would be local to one ruleflow
(instance). Note that these variables are still on the TODO list as
well.</FONT></DIV>

<DIV>> 1) Yes kris is still working on the decision stuff for
ruleflow.</DIV>
<DIV>Some of the stuff is already partially implemented, but an (X)OR split
(where you can define which path(s) to follow based on some conditions) is
still on the TODO list.<BR><BR>> 3) The Eclipse GUI ruleflow builder
doesn't seem to allow loops in the flow.</DIV>
<DIV>It does support the creation of loops: create an XOR split as the
starting point of your loop, you can then always create nodes that link back
to this starting point, resulting in a loop. Note that looping kind of
depends on the (X)OR split as well, as that would allow you to exit the loop
in specific conditions (now you will probably create an endless loop).
I hope I'll be able to add that piece of functionality pretty soon to
trunk.</DIV>
