If a rule is declared as "auto-focus", then when it is activated, it
will change the focus module to its own module. But in the absence of
this declaration, an activated rule in a non-focused module will just
sit and wait for its module to be focused again; it will not fire
immediately,

Hi everyone,
I'm currently integrating JESS into my web application and the
architecture
is typical; running rete.runUntilHalt() and asserting a shadow fact
for an
incoming HTTP request. But as more and more rules are developed, I'm
thinking to partition the rules into modules.
Now, suppose I have 2 module, moduleA and moduleB, and some rules are
defined to match the same set of shadow facts on the LHS. In
essence, I
could "switch" the execution logic by either focusing moduleA or
moduleB,
and the decision for which module gaining control is depends on the
screen
the user is in.
However, there is an incoming the fact which should be running in
moduleB
but there might be chances that rule engine is processing another
requests
and moduleA is the current focus; if the incoming fact is assert at
that
time, it might be running moduleA instead of moduleB.
So, might I confirm if the above scenario would happen? Is there any
workarounds to avoid the unnatural execution? What would be the
orthodox way
to implement the module control flow then? Any help or opinion
would be
appreciated.
Thank you very much, everybody!!
Best Regards,
folderman
