Aj4:support initialize backing bean

Question

Hi,
I am a newbi in JSF and aj4.I have used ajs:support tag to do a server side validation (a business validation) ,invoking a backing bean method.
What I have observed is ,when ever the ajax call happened for this validation method , the init() method of the backing bean is getting executed.I have annoted the init with @postConstruct.This is required for me.
Please find the code below
jsp
<a4j:support event="onblur" action="#{accgpBean.validateId}" reRender="idValidMsg" immediate="true"/>
<h:outputText  binding="#{accgpBean.idValidMsg}" id="idValidMsg"/>Backing bean
@PostConstruct
     void init(){
          AccountGroup grp=new AccountGroup();
          grp.setAccntSuperGrp(new AccountGroup());
          this.setAccntGrp(grp);
          System.out.println("Retrieving the accnt grp>>>");
          accountGroupList=accountService.listSuperGroup();
public String validateId(){
        System.out.println("Invoked validation method>>>");
        idValidMsg.setValue("Invalid Id");
        return null;
   }Can anybody suggest,how do I turn off the invokation of init() on the ajax requests ?
Thanks in Advance
