[TYPO3-community] Community extension issues

[Cray Flatline]

I try to get deeper into Community extension
(http://forge.typo3.org/projects/show/extension-community). I get it
from SVN and install on the one of my sites. I placed community
extension on the some page and set up default TS setup.


When I select Group Profile: Member List, it  gives me
Fatal error: Call to a member function isAdmin() on a non-object in
/home/imeibase/public_html/typo3conf/ext/community/controller/groupprofile/class.tx_community_controller_groupprofile_memberlistwidget.php
on line 97

When I select User Profile: Personal Information, it gives me


Fatal error: Call to a member function getUid() on a non-object in
/home/imeibase/public_html/typo3conf/ext/community/controller/userprofile/class.tx_community_controller_userprofile_personalinformationwidget.php
on line 70

What i miss? Please Help me.


WBR,
