Unable to add tab in datacenter or any other vmwre mangaed object related item view.

Hi,

  We are developing a plugin similar as demonstrated in chassis app.

  In our Custom object we have more object view where we show host, datacenter, virtualmachine listView.

  Similarly we want to show our custom object list in datacenter, datastore and host related item.

Tried with below sample code but .

<extension id="xxx.xxx.xxx.relateditems.specs.host">

   <extendedPoint>vise.relateditems.specs</extendedPoint>

   <object>

      <type>HostSystem</type>

      <relationsViewId>vsphere.core.host.related</relationsViewId>

      <relationSpecs>

         <com.vmware.ui.relateditems.model.RelationSpec>

            <id>XXXForHost</id>

            <icon>#{XXX}</icon>

            <label>Test Plugin relation</label>

            <relationXXX</relation>

            <targetType>XXX:XXX</targetType>

            <listViewId>xxx.xxx.xxx.list</listViewId>

         </com.vmware.ui.relateditems.model.RelationSpec>

      </relationSpecs>

   </object>

</extension>

IN HTML CLIENT 6.7

   Is it possible to add new tab in datacenter/host/datastore related view ?

   Any other place in vmwre workspace object where i can show my custom object list ?
