Notice: Undefined index: access callback in commons_wikis_menu_alter() (line 50 of commons_wikis/commons_wikis.module).

Can you post steps to reproduce? I'm not able to do so. In general, Commons Wikis should be enabled as part of the default Commons install.

Hi....

I think this may have something to do with the bean module. I started getting it after enabling Bean and Bean Admin UI (7.x-1.1) on Commons 7.x-3.2.

Then, enabling another module produces this error...

I am also seeing this bug, or at least the access callback one. I haven't seen the title_value issue from #3.

Steps to reproduce:
Start with a fresh Drupal Commons site (I used the 7.x-3.2 tarball).
Download the Bean module.
Enable Bean (bean) and Bean Admin UI (bean_admin_ui).
Visit Structure -> Block Types, and click the Add block type button.
Fill in a value for the Label field (and maybe Description) and save the block type.

That should generate the notice in question. It should be in the message area after saving, and also in the recent logs. (Anything that triggers hook_menu_alter() should cause the error, though.)

Looking at commons_wikis_menu_alter(), it looks like the function is trying to find nodes which use revisions by looking for paths containing "revisions". And if such a path is found, any existing "access callback" on that path is replaced with "commons_wikis_user_revision_access" (with the old "access callback" being stored in "access arguments").

I think the actual "Undefined index" bug happens because not all of Bean's paths have explicit access callbacks set. I think some of the access callbacks are inherited instead. You can make the bug go away if you check that "$items[$route]['access callback']" is set before trying to add it to "access arguments".

I think there's a further issue in that Bean blocks are entities (defined via the entity API) and use revisions, so they get caught by commons_wikis_menu_alter(), but they aren't nodes. So it may not be appropriate to replace their callbacks.

Setting to fixed, as I cannot reproduce this on latest dev.
