Deny ROLE_USER create and modify scheduling

[negracula]

Hello, i need to prevent scheduling reports by normal users, even modify a previous schedule made by ROLE_ADMINISTRATOR. Only can scheduling the ROLE_ADMINISTRATOR.

 

I've follow this guide http://community.jaspersoft.com/wiki/how-customize-navigation-resource-menu-right-click-resource to prevent use the scheduling action and it only works partially, users can't create a schedule using context menu (right click) but they can modify,eliminate a previous schedule. how? By using a link (clock icon) in list of reports that have a previous schedule.

 

Anyone knows a solution to prevent this? 

 

Thanks a lot.
