I am trying to customize the Employees view via inherited view. Currently, there are a few tabs in the Employee page: Information/.../DriverInfo/TechnicianInfo. ( i added the two pages : DriverInfo & TechnicianInfo to my notebook ) 

For the user 'Administrator', i don't need both DriverInfo and TechnicianInfo.at first, i tried 

<page string="DriverInfo" position="attributes">

    <attribute name='invisible'>1</attribute>

</page>but instead of hiding it, a new page was created with the value 1 !!please kindly,  advise how I could achieve this.

Thanks a lot
