Strange behaviour with permissions

Permalink
I create a page in code and want only the creator (which is a registerd user) to be able to add, admin and delete blocks in the main area.

Strange thing i that the user when logged in can move, add and admin blocks but is not able to delete..

Any help? I realy don't understand what is going wrong.

Thnx in advance...


$u = new User();
            $pData = array('uID' => $u->getUserID(), 'pkgID' => 0, 'cName' => $tab->tName, 'cHandle' => $ch->uuid(), 'cDescription' => $tab->tName);
            $oPage = Page::getByPath('/pages');
            $ct = CollectionType::getByHandle('facebook_page');
            $newPage = $oPage->add($ct, $pData);
            Loader::model('attribute/categories/collection');
            $cak = CollectionAttributeKey::getByHandle('campaignid');
            $tak = CollectionAttributeKey::getByHandle('tabid');
            $pl = PageTheme::getByID(7);
            $newPage->setTheme($pl);
            $newPage->addAttribute($tak, $tab->ID);
            // Assign permissions to page so only the new user can view
            $pxml->guests['canRead'] = false;
            $pxml->registered['canRead'] = false;
            $pxml->group[0]['gID'] = ADMIN_GROUP_ID;
