Hi all,
after an upgrade from 3.6.2 to 3.7 I get an error
in the admin siteaccess view.
It happens in Content structure page, when I disable Relations block.
No override for templates of this page were made.

This is the error message:

Error: eZTemplate design/admin/templates/windows.tpl:17[0]

No such attribute for array(4): show_relations
Choose one of following: offset, year, month, day

My system info:

Apache/1.3.33 (Debian GNU/Linux)
PHP Version: 4.3.10-2

upgraded to 4.4.0-4 version; the error still exists...

all cache cleaned . The problem is in the new template file design/admin/templates/windows.tpl

From the previous version the code changed in rows 17-18

<b>(ver 3.6.2)</b>

{* Relations window. *}
{section show=ezpreference('admin_navigation_relations')}
    {include uri='design:relations.tpl'}
{/section}

<b>(ver 3.7)</b>

{* Relations window. *}
{section show=or( ezpreference( 'admin_navigation_relations' ),
                  $view_parameters.show_relations)}
    {include uri='design:relations.tpl'}
{/section}

...so when $view_parameters.show_relations has non value it returns an error.
But I don't know why $view_parameters.show_relations has non value...
