[rules-users] Multiple rule violation

[Wolfgang Laun]

That's all very vague (and please check "violated" in your
dictionary), but see below:

I can't say much without seeing the rule. Clearly, if there is only
one obj2 and if it is updated in both "then" parts, it may not reflect
the actual state of affairs.

As the purpose of obj2 is not clear, I  refrain from suggesting
anything. If obj2 should contain data depending on the rule, you'll
need one for each rule. If, however, it should reflect the changes
made on obj1, you need one obj2 for each obj1, and it should, somehow,
be related to it.

Unless you interfere, it does not stop working if there are still
unfired rules with true (matching) left hand sides.

Q1: It depends. Q2: Yes, as the documentation says...

Absolutely unclear.
