Hi Everyone,

I have a AjaxObserveField that calls a AjaxUpdateContainer with unique id. But the Ajax update container returns empty response from the server at times. So the field on the UI sudden  vanishes from the form. I have the code below. Any suggestions are appreciated.

<formRow>
            <divColumn1 style="text-indent:135px;">Registration Approval Status</divColumn1>
             <span><wo:popUpButton noSelectionString="Any" list="$regApprovalStatusList" item="$regApprovalStatusItem" displayString="$regApprovalStatusItem.displayName" id="regtestid" selection="$selectedRegApprovalStatus"/>
               <wo:AjaxObserveField observeFieldID="regtestid" updateContainerID="regYearContainer" fullSubmit="$false"/>
            </span>
            &nbsp;&nbsp;
         <wo:AjaxUpdateContainer id="regYearContainer" elementName="span" class="dataLabel">      
                <wo:if condition="$regStatusExists">
               <wo:str value="Year:" class="dataLabel"/>
               <wo:WOPopUpButton list="$allYears" item="$year" displayString="$year.yearString" selection="$regYearSelected" />
               </wo:if>
              
           </wo:AjaxUpdateContainer> 
        </formRow>

Thanks
