JESS: RE: Handling of duplicate rule names

[Gyhra, Norman (Student Assistant)]

Hi Ernest!

Thanks for your answer.

I had two rules with the same name.

The second one would not fire before the
first one had fired (it would go too far to describe
the reasons for that)

Therefore I assumed that the rules would not fire at all.

Instead, the first rule was deleted (as u say) and
the second one never fired.

Nevertheless, it would be nice if I get a warning
when rules are silently deleted. :)
Sometimes I just use copy&paste to create new rules
and there is the danger that I do not remember the
duplicate rule name.
I assume that others may have had similar problems.

Of course, it is not really vital to get a warning or
error. However, it could already have saved some time
and may possibly do it in the future.

Regards,
Norman Gyhra

Hi Norman,

The behaviour is supposed to be as documented in the last paragraph of
section 2.8.1 of the manual:

"Rules are uniquely identified by their name. If a rule named my-rule
exists, and you define another rule named my-rule, the first version
is deleted and will not fire again, even if it was activated at the
time the new version was defined."

If you've got a case where the behaviour is otherwise, you've found a
bug. Please try to produce the simplest input file that shows the
problem -- the simpler the better -- and send it along. Thanks!
