notification issue

I am querying latest version of a part. Here is the code i am using:

1. Queryspec:

    QuerySpec querySpec = new wt.query.QuerySpec(WTPart.class);

    querySpec.appendWhere(new wt.query.SearchCondition(WTPart.class, "master>number", wt.query.SearchCondition.EQUAL, partNumber, true), new int[]{0});

    querySpec.appendAnd();

    querySpec.appendWhere(new wt.query.SearchCondition(WTPart.class,"view.key.id",wt.query.SearchCondition.EQUAL,viewNum), new int[]{0});

    QueryResult queryResult = PersistenceHelper.manager.find((StatementSpec)querySpec);

    if(queryResult.hasMoreElements())

    {

        part = (WTPart) PartHelper.getLatestVersion((WTPart) queryResult.nextElement());

    }

  2. Info Engine Task:

<ie:webject name="Search-Objects" type="OBJ">

   <ie:param name="INSTANCE" data="<%=processor%>"/>

  <ie:param name="ATTRIBUTE" data="name,number,view.id^name" delim=","/>

  <ie:param name="dbUser" data="wcadmin"/>

  <ie:param name="PassWd" data="wcadmin"/>

  <ie:param name="WHERE" data="(number='<%=partNumber%>')"/>

  <ie:param name="WHERE" data="(view.id^name='<%=viewName%>')"/>

  <ie:param name="VERSION" data="LATEST"/>

  <ie:param name="TYPE" data="WCTYPE|wt.part.WTPart"/>

  <ie:param name="GROUP_OUT" data="partInfo"/>

</ie:webject>

All the objects have Basic lifecycle.
