In magnolia-enterprise-4.5-beta3 user eric cannot initiate workflow requests, My error log is attached. On a fresh reinstall of magnolia-enterprise-bundle-4.5-beta3-tomcat-bundle.zip I did the following:

• Login as superuser and created new page demo-project/test.
• Login as eric and tried to activate (send workflow request). The workflow comment dialog opens, but on save an error dialog "can't version: Workspace access denied", opens.
• Login as superuser and activated new page in Website. Workflow process worked as expected..
• Login as peter and clicked Proceed in Inbox. Page is activated successfully.
