[rules-users] User and/or Code problem with insert/retract and salience

We have 5 rules that are firing out of salience order for a particular set of 4 objects. The rules have a branch on the RHS which sometimes retracts the A object. There are reasons why the branch is not in the LHS not shown in this sample. The 5 rules are like the following. The salience values are 70, 65, 60, 55, 50 rule "a1" salience 70 agenda-group "b" when a: A(name customevaluator "X") B(name = "B") then // sometimes retract end There is one B object. Another rule fires (at salience 0) and inserts 4 A objects. 1) A1 runs rule at salience 70 and is retracted 2) A2 runs rule at salience 70 and is not retracted 3) A3 runs rule at salience 70 and is retracted 4) A4 runs rule at salience 70 and is not retracted 5) A4 runs rule at salience 65 and is retracted 6) A2 runs rule at salience 50 and is retracted I would have expected step 6 to have A2 run at salience 65 but instead it went from 70 to 50 skipping 60 and 65. Is my understanding of the rule rhs firing order wrong? I'm using a 5.1 snapshot from Dec 23 2009. I searched the JIRA and did not see anything related.
