[sandhyaradhakrishnan]

when onselect event is fired after selecting suggestion ,it is setting userId to myMB

but the value of input text[id=suggest_inpu] is getting cleared in the UI

<h:inputText id="suggest_input" />

   <rich:suggestionbox for="suggest_input" minChars="1"

       fetchValue="" nothingLabel="no entry found"

         suggestionAction="#{myMB.suggestData}" var="suggest">

         <h:column>

            <h:outputText value="#{suggest.firstname}" />

         </h:column>

         <h:column>

            <h:outputText value="#{suggest.lastname}" />

         </h:column>

            <a4j:support ajaxSingle="true" event="onselect"

                action="#{myMB.refreshData}" reRender="data_id">

            <f:setPropertyActionListener value="#{suggest.userID}"

                    target="#{myMB.userID}" />

         </a4j:support>

  </rich:suggestionbox>
