When chaining together four rules in such a way that no one rule is fired more 
than once and each rule is excuted squentially based upon a priority, the 
second rule does not fire.

Here are the 4 rules.

    <!-- priority and no recursive rule -->
   <rule name="AssignTask" salience="-1" no-loop="true">
      <!-- What is being passed into the rule -->
      <parameter identifier="taskVO1">
         <class>TaskVO</class>
      </parameter>
       <!--  What conditions must be true before rule is asserted -->
      <java:condition>taskVO1.getIdentifiersList() != null || 
taskVO1.isIdentifiersListEmpty() == false</java:condition>
      <java:condition>taskVO1.getActionStep().equalsIgnoreCase("AWAIT EVAL")== 
true </java:condition>
      <java:condition>taskVO1.containsIdentifier("CONTRACT", "S#1234567890") == 
true</java:condition>
      
      <!-- What does the rule does for us -->
      <java:consequence>
          System.out.println("*****************************  in consequence for 
rule1");
          taskVO1.setDepartment("DPT1");
          taskVO1.setDptCode(lookupDeptCode("DPT1"));
          taskVO1.setWorkBasket("rray");
          taskVO1.setTaskType("ADFPAYCHK");
          taskVO1.setTskCode(lookupTaskTypeCode("ADFPAYCHK"));
          taskVO1.setActionStep("INDEX");
          taskVO1.setActCode(lookupActStepCode("INDEX"));
          taskVO1.setStatus("OPEN");
          //printTaskVO(taskVO1);
          <!-- Firing any other rules based on changes -->
          drools.modifyObject(taskVO1);
      </java:consequence>    
   </rule>
   
      <!-- priority and no recursive rule -->
   <rule name="AuditTask" salience="0" no-loop="true">
      <!-- What is being passed into the rule -->

Only the first rule is fired.
