After installing FOM 4.0.2 Hotfix 4, 5 or 6 then the Postinstallation Tasks from the readme file have to be followed. Certain changes are required to the ope_config.xml file.
    
The readme file says the following:
    
==========================================================
    b) Change the ope_config.xml file for sequencedRule by adding the following
          condition and action:
          
    <sequencedRule>
    <action actionType="bean">
    <actionBean beanId="publishOfferResponse" methodName="execute"
    interface="com.tibco.aff.eca.base.Action"/>
    </action>
    </sequencedRule>
    <sequencedRule>
    <condition conditionType="bean">
    <conditionBean beanId="postProcessOfferCondition" methodName="evaluate"
    interface="com.tibco.aff.eca.base.Condition"/>
    </condition>
    <action actionType="bean">
    <actionBean beanId="postProcessOfferResponse" methodName="execute"
    interface="com.tibco.aff.eca.base.Action"/>
    </action>                    
    </sequencedRule>
==========================================================
    
The sequencedRule must be added to the offerResponseRule ruleSet. I have attached a sample ope_config.xml for clarity.
