Could you give exact way how to add existing object (not a section, but additional one) to the portal?
1. I add the object to lookup 'List of objects available for portal users'
2. I add all fields of the object to lookup 'List of schema fields for portal access'
3. I add list with this object to the Main page of the portal
4. Object has no restriction of access rights (Operations and Records)
But portal user on the Main page doesn't see any data in that object - just empty list.
What else should be done?
