How to restrict to empty trashcan

Question

I would like to restrict emptying of trashcan by ordinary users. Permission to empty trashcan should have only users with admin role.

Is there any way how to solve this issue? For example to implement Java method used as evaluator before button displaying? Or any other sophisticated way, solution or implementation, how to secure this resctriction?

Thanks

You can add your restrictions to Share UI and to Repository service.

In order to hide the Share UI button for non Admin users, you can extend Alfresco.ConsoleTrashcan YUI object:

https://github.com/Alfresco/share/blob/alfresco-share-parent-6.2.0/share/src/main/webapp/components/console/trashcan.js#L47

Regarding Repository service, you can create a new NodeServicePolicies.onDeleteNode behaviour listening to sys:archived nodes.
