[Need Help] Getting an error while selecting particular object instance (you have no privileges to view this object or it does not exit)

When I select any object instance (Arr1/Arr2/Arr3) from object Navigator ,I am getting an error called "you have no privileges to view this object or it does not exit" in work space area.

we have defined the template  "vsphere.core.inventory.objectViewTemplate" in plugin.xml.

And also we have written the business logic in my adapter class(which is implements DataProviderAdapter) same as like chaasisRackVsphere sample.

we are not sure why specific object instance is not being displayed.Please refer the screen shot.

Please suggest me,what is missing in it.

Thanks and regards,
