ACL for touch UI content authoring
What is the ACL settings required for a content author to edit content in touch UI. Is it different from classic UI? We created a user and provided read only access to "apps","bin","etc" and "libs". Read,modify and delete access for "content". When we try authoring content in classic UI with this user, it is working fine. However when we try authoring content in touch UI, we get null pointer exception in various files in com.granite.ui. Whereas for an admin user content authoring works fine in touch UI. Is this an issue with the ACL settings for the user? Do we need to provide access to any specific folder for touch UI authoring?
