Yes it's slower. Using globals in this manner is not adviseable - if a
global is used in Rete it must be considered final. If you alter the
global's value and you use it in the manner you describe you will make
the Rete network invalid. Its too late to add this feature now. Also I
may come up with another mechanism which is specified at
ruleBase.addPackage( ... ) time - i.e. proper finalised parameters. But
this is now 3.1 territory.

Hi,
I wanted to know if it is possible to support the use
of globals in column constraint, like this:
global java.lang.String value
rule "Sample rule"
when
# this does not work, because drools expects
# value to be a declaration
MyBean( prop == value)
then
System.out.println("fired");
end
The motivation is to have a kind of "parameterized"
rule, where parameters will be provided as globals.
I'm working around this by doing:
Exception( m : message -> (m == param) )
but this is slower, right?
Thanks,
Yuesong
