[xwiki-users] Panel does not appear

Hello all! There is a problem with a panel, which does not appear for a user. Here is what I have done: Xwiki Enterprise 2.0.3.24848 0. Login as User in Admingroup 1. Created a space "SpaceA" with several pages 2. Created a group "GroupA" 3. Created a user "UserA" 4. Put UserA in GroupA 5. Gave edit and view rights for SpaceA to GroupA 6. Changed Page Layout to Left column 7. Added only one panel PanelA which shows the documents of this page 8. All works fine 9. Login as UserA 10. Can only see documents in SpaceA but cannot see PanelA Even if I give all rights to UserA for SpaceA I cannot see PanelA. If I want to administrate SpaceA as UserA and choose the panels section I became an error: "Topic Panels.PanelWizard does not exist". Sections Presentation and Rights are working fine. Does someone know this behaviour? Can anybody give a hint or help me? Greetings Dirk
