Re: [rules-users] Can I change the value of a global in a rule consequence?
Done right, it works.
The variable m you have in a consequence functions very much like a
value parameter, set anew for each execution of each consequence.
Actually, all globals reside in some central repository from where they
are fed into any consequence execution.
Therefore, there is just one way of setting a global.

The manual says "It is strongly discouraged to set or change a

I tried this:
========================
global Integer m;
declare DoneInit end
rule "init"
when
then
insert(new DoneInit());
System.out.println("m from Java: " + m);
m = 100;
System.out.println("m modified in init: " + m);
end
rule "use it"
when
DoneInit()
then
System.out.println("use m: " + m);
end
==========================
and got this output:
m from Java: 13
m modified in init: 100
use m: 13
Is this the expected behavior? I'm in a stateless session in case that
matters.
