Hi there. I'm trying to get automatic update of rules working in
my
project, and seem to
have run into a problem. As far as I can tell, automatic polling and
updating is turned
on, and claims to update the knowledgebase, but changes to the rules
don't seem to have
any effect. A simple example - if I add the rule:
rule "TestRule"
dialect "mvel"
when
then
System.out.println("Hello, world!");
end
And start my application, I get:
Firing all rules...
Hello, world!
All rules fired.
As expected. If I then change the rule as follows:
rule "TestRule"
dialect "mvel"
when
then
System.out.println("I have changed!");
end
I get this output (timestamps trimmed for readability):

So, this makes it seem like everything has worked. However, if I
insert a new fact and
fire all rules...
Inserting new fact...
Hello, World!
So, it hasn't worked. What might I have done wrong?
