Webject to get the latest design view of a part

I'm trying to get the latest design view of a part with a webject query.

I've tried the following, but it continues to return the manufacturing view if it is later than the design rev.

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

  <ie:param name="INSTANCE"  data="com.fncorp.sine.Windchill"/>

  <ie:param name="authorization" data="$(@SERVER[]AUTHORIZATION[0])"/>

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

  <ie:param name="attribute"  data="name,number,version,iteration,view,group" delim=","/>

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

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

  <ie:param name="VIEW"   data="Design"/>

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

  <ie:param name="group_out"  data="objectSearched"/>

    </ie:webject>
