Need help getting around the following error: JBO-27101: Attempt to access dead entity in EO.

Question

Hi everyone,
My logic in prepareForDML() updates some attributes (shown in the snippet below) based on whether an insert or update is taking place. But, when I delete a line, I get the following error: JBO-27101: Attempt to access dead entity in EO. So far, I have not been able to catch this error.
        if (operation == DML_INSERT) {
            setLineId((new SequenceImpl("eo_s",
                                        getDBTransaction()).getSequenceNumber()));
            setCreatedBy(createdBy);
            setCreationDate(currentDateAndTime);
            setLastUpdatedBy(lastUpdatedBy);
            setLastUpdateDate(currentDateAndTime);
        } else if (operation == DML_UPDATE) {
            setLastUpdatedBy(lastUpdatedBy);
            setLastUpdateDate(currentDateAndTime);
Any advice would be appreciated. Thanks!
James

Hi Timo,
Thanks for responding. Whenever I delete a line and commit, I get the error. And, since inserts and updates are all that I am interested in, I did not think that I needed deletion logic. The VO contains several EOs, but all are reference EOs that cannot be updated except for the main EO.
Here is the entire prepareForDML() method:
    protected void prepareForDML(int operation, TransactionEvent e) {
        // BEGIN Initial Version
        // Using prepareForDML is a best practice (versus doDML).
        ApplicationModule am;
        boolean lineIsValid;
        byte entityState;
        byte postState;
        Date currentDateAndTime;
        Date weekEndingDate;
        Number createdBy;
        Number lastUpdatedBy;
        String amConfiguration;
        String amDefinition;
        String entityStateText;
        String operationText;
        String postStateText;
        ServicesAMImpl servicesAMImpl;

        // am = Configuration.createRootApplicationModule(amDefinition, amConfiguration);
        createdBy = new Number(-1); // TODO fnd_profile.value('USERNAME')
        entityState = getEntityState();      
        entityStateText = null;
        operationText = null;
        postState = getPostState();
        postStateText = null;
        lastUpdatedBy =
                new Number(-1); // TODO fnd_profile.value('USERNAME'); is there a last login id?
        // servicesAMImpl = (ServicesAMImpl)am;
        // lineIsValid = servicesAMImpl.callValidateLineProcedure(getBillable());
        timeStamp = new Timestamp(System.currentTimeMillis());
        currentDateAndTime = new Date(timeStamp);
        // TODO Should weekEndingDate be in the callValidateLineProcedure()?
        weekEndingDate =
                commonCode.nextDay(getActivityDate(), Calendar.THURSDAY);
