rich:comboBox fails to reRender due to rich:ajaxValidator

[Adam Greenberg]

Hi,

So I have a situation where the selection from the drop down in rich:comboBox A should cause rich:comboBox B to reRender, thus removing any values previously selected and displaying a blank comboBox. However, what seems to be due (ie, when I remove the code it works like it should) to a rich:ajaxValidator rich:comboBox B retains the value previous selected. rich:comboBox A being id="org", and rich:comboBox B being id="orgiunit" Below is the code:

  <rich:comboBox id="org"  required="true" selectFirstOnUpdate="false" defaultLabel="Org" value="#{contractorMBean.org}" valueChangeListener="#{contractorMBean.orgValueChanged}" enableManualInput="false" width="155px">
                  <f:selectItems value="#{contractorMBean.orgs}" />
                  <a4j:support event="onselect" reRender="orgiunit,bsorg,shipTo,bAddr,supervisor" ajaxSingle="true"/>
              </rich:comboBox>
              <rich:message for="org" errorClass="errClass"> 
                  <f:facet name="errorMarker">
                     <h:graphicImage url="/images/error.GIF"/>
                 </f:facet>
               </rich:message>
             <h:outputText styleClass="red"   value="*"/>

              <h:outputText value="Organization Unit:"/>

<rich:comboBox id="orgiunit" rendered="true"   enableManualInput="false"   required="true"    selectFirstOnUpdate="false" defaultLabel="Org Unit" value="#{contractorMBean.orgUnit}" valueChangeListener="#{contractorMBean.orgUnitValueChanged}" width="155px">
                  <f:selectItems value="#{contractorMBean.orgUnits}" />
                  <a4j:support event="onselect"  reRender="bsorg,shipTo,bAddr,supervisor" ajaxSingle="true"/>
                 <rich:ajaxValidator event="onblur" />
              </rich:comboBox>

              <rich:message for="orgiunit" errorClass="errClass"  showDetail="true"> 
                  <f:facet name="errorMarker">
                     <h:graphicImage url="/images/error.GIF"/>
                 </f:facet>
              </rich:message>  

You guys were nothing short of AWESOME last time in helping me with my problem and I'm hoping you can do it again. Many thanks in advance.
