Warning: Invalid argument supplied for foreach() in entity_forms() line 505 of entity.module

I'm also seeing this once per page with the Media Development Profile.

Problematic part of code is:

  foreach (entity_ui_controller() as $controller) { # line 505
    $forms += $controller->hook_forms();
  }

entity_ui_controller() returns NULL which is obviously not an array. :P

I tried some various dvm()ing inside entity_ui_controller(). The gist is that the format of the entity_get_info() array has changed. Entity's looking for stuff at $info['admin ui']['path'] and the 'admin ui' index no longer exists (it's now 'admin', underneath an $entity_type index). I tried re-jiggering the checks in that function to match the output of entity_get_info() and then I get Fatal error: Call to undefined method UserController::hook_form() and the like, which I don't really understand, and certainly isn't an improvement. ;P

Incidentally, I got a similar error during installation on entity_menu() for the same reason.

And since something seems to be just flat-out wrong here, increasing priority.

Same here. Thx webchik.

Given other modules use this API this should be a priority for the developer.

maybe something to do with D7B2?

Sry, I introduced this problem with #920546: Entity CRUD generic UI. I think I already fixed that with http://drupal.org/cvs?commit=441076.

Ok. So I had installed the dev version.

I just reverted back to beta1 and all seems good.

I have got:
Warning: Invalid argument supplied for foreach() in entity_menu() (line486 of /var/www/html/modules/entity/entity.module)
after I enable and save the Entity CRUD API module.
