Hi all. I am busy upgrading from mendix 7 to 8. After the upgrade all is going well until i try and use $currentUser in a java action. Seem to be null. Where and when is currentUser set during login?   com.mendix.core.CoreException: com.mendix.modules.microflowengine.MicroflowException: Failed to evaluate expression, error occurred on line 1, character 1 $currentUser ^                 at Administration.Log_UserChanges (JavaAction : 'AuditLogUser')                 at Administration.SaveAccount (SubMicroflow : 'Log_UserChanges')
