Getting nullpointer exception with PrimeFaces autocomplete

Question

Having problems with autocomplete primefaces. When I select any one of the autocomplete tag, first time it works without any issue. But when I select it for second time it throws below error.

Below is the code

<tr:inputDate id="endDate" value="#{projectMgdBean.addProject.end_Date }" required="true" requiredMessageDetail="end Date Missing"/>
<tr:outputLabel value="Test Efforts:" for="efforts"/>
<tr:inputText id="efforts" value="#{projectMgdBean.addProject.efforts }" required="false" requiredMessageDetail="end Date Missing"/>
<p:outputLabel id="countryLabel" value="Tester: " />
<h:panelGroup>
<h:panelGrid>
<p:autoComplete id="tester1" vallue="#{projectMgdBean.addProject.tester1}" completeMethod="#{projectMgdBean.getEmails()}" cache="true"/>
<p:autoComplete id="tester2" vallue="#{projectMgdBean.addProject.tester2}" completeMethod="#{projectMgdBean.getEmails1()}"/>
<p:autoComplete id="tester3" vallue="#{projectMgdBean.addProject.tester3}" completeMethod="#{projectMgdBean.getEmails2()}" />
</h:panelGrid>
</h:panelGroup>
</h:panelGrid>

I am using JSF 1.2 and primeFaces 5.0
