taxonomy_treemenu module/views/Cannot use string offset as an array

28 Jul 2009

      I'm using the most recent versions of Drupal, Views and Taxonomy  
Treemenu.

The taxonomy treemenus are generating successfully, using the default  
view (taxonomy_router_term).

I'm having problems accessing the content when I'm NOT logged in as  
admin.  I'm using the default view (taxonomy_router_node) and access  
is set to unrestricted.

The 'authenticated user' (which I understand is everyone that is not  
logged in?) gets
Fatal error: Cannot use string offset as an array in /sites/all/ 
modules/taxonomy_treemenu/taxonomy_treemenu.module on line 2367
whereas the admin user gets to see the content.

If I give the authenticated user 'Administer Nodes' permissions I do  
not get the error and I do see the content, however that means that  
anyone can create content, which is not what I want.  Interestingly  
applying all create, delete, edit permissions (but NOT administer  
nodes) brings back the error.

This is the code.

     case "taxmenu/%/node/%/%":
         //Treemenus have no node links. To control exansion, we  
target the
         //parent tid link.
         $item['href'] = 'category/' . $item['page_arguments'][0] 
['vid'] . $item['page_arguments'][1]['parent_path'];
         break;

Specifically, line 2367 is
         $item['href'] = 'category/' . $item['page_arguments'][0] 
['vid'] . $item['page_arguments'][1]['parent_path'];

Logged in as admin $item['page_arguments'] returns:
Array
(
     [0] => Array
         (
             [menu_name] => menu-ol-hlp
             [title] => Online Help
             [description] => Jane Systems online help
             [vid] => 13
             [tid] => 0
             [options] => a:3:{s:6:"filter";a:0:{}s:6:"fields";a:0:{}s: 
4:"sort";a:1:{s:3:"nid";a:1:{s:5:"order";s:3:"ASC";}}}
         )

     [1] => Array
         (
             [0] => Array
                 (
                     [tid] => 55
                     [title] => System Setup
                 )

             [1] => Array
                 (
                     [tid] => 68
                     [title] => Authorisation Centre
                 )

             [parent_path] => /55/68
         )

     [2] => 25
)
But when I'm not logged in I get

a:3:{i:0;i:1;i:1;i:3;i:2;i:4;}
I can see that $item['page_arguments']  isn't being turned into an  
array, but I can't see why.

I've been trying to trace back $router_items to see how it gets  
generated, but I can't seem to find it.

I'd really appreciate any help.

Thanks
