No submenu block showing

I also stumbled over this bug or something like it.

For getting some required informations about the current item (received through menu_get_item()) the program matches $current_router_item['href'] against the database field menu_links.link_path. The Problem (in my case) is that in $current_router_item['href'] are no "+"s in the URL but they are in menu_links.link_path. The result is, that there is no match between the menu items and the subtree is not displayed.

I've written a small workaround. I am fairly new to drupal so i think this is not the final solution, but it works for me.

I have noticed the 2nd level disappearing when I turn on block caching in the performance site config. Does turning off block cache fix the problem for you too?

having the same problem with latest drupal 6.8 installed...

i think i figured out problems. its only problem if u use VIEWS with this module. well it works fine with wiews unless you have passed argument in your view

so if u have view with page view set up like "myview" and then u add some menu item that says myview/myargument it doesnt work and drupal doesnt rendered it ok, i say drupal as it's menu.inc file problem in fact its this line in block module

$second_level_tree = menu_block_split_second_level_tree(menu_tree_page_data($menu_name), $parent);

where menu_tree_page_data is called then "below" array which tells which menu items are below this one, is not populated for menu items where u have "views link" with argument. So u should hardcore this views and then u wont have problem. Suggesting you set default variable for views and make its name myview/something and it should work then when u put myview/somthing in as menu item. Fixing this could be even core or views problem so i wont get into this, i just found out where it is :)

ehh crayze stuff(overworking) forget everything i said, i found out what was the problem. It works in other parts but not here.

you have to assign to your paths in view(s) /% for argument(s) as views say to you but you maybe didnt listen as i didnt. It usually works if you dont add %, but here it goes into problems. so make your view paths like "myview/%" where % stands for argument and there you have solution i suppose :-)
