Entering a Value and Tabbing out of af:inputListOfValues displays the wrong value

Question

Good morning. I am having an issue with the autosubmit and tabbing out of af:inputListOfValues in my code.
Problem: When I type in a valid value and tab out of the field, it ignores the value I entered and displays whatever the first list in the query result instead regardless of the value I typed.
My code snippet. What it does is simply an LoV search of Employee No attached to an entity attribute and depending on selection, it will display the Employee Name within the page. (it also retrieves a table view depending what employee number was entered)
<af:inputListOfValues id="empNoId"
             popupTitle="Search and Select: #{bindings.EmpNo.hints.label}"
              value="#{bindings.EmpNo.inputValue}"
              label="#{bindings.EmpNo.hints.label}"
              model="#{bindings.EmpNo.listOfValuesModel}"
              required="#{bindings.EmpNo.hints.mandatory}"
              columns="#{bindings.EmpNo.hints.displayWidth}"
             shortDesc="#{bindings.EmpNo.hints.tooltip}"
               binding="#{workLocationBean.txtEmpNo}"
              partialTriggers="id1"
             valueChangeListener="{bean.onEmpNoChange}"    
             autoSubmit="true">
        <f:validator binding="#{bindings.EmpNo.validator}"/>
  </af:inputListOfValues>
Other things to note:
When I enter a valid employee number and click anywhere in the page (not TAB), it behaves correctly.
I have been trying to figure this out for days. Even my valueChangeListener gets the wrong value (when I do System.out) when I tab out so I am not sure where to catch it and replace it with the correct value.
Thank you.

This usually happens when primary key is not set in view object used by LOV.
