Wrong datatype PHP warning while saving settings

I am receiving the same error.

in_array() [function.in-array]: Wrong datatype for second argument in /web/six/sites/all/modules/content_access/content_access.admin.inc on line 369.

but only when I try to update the role from the roles -> edit permissions. When I edit it from the permissions menu I do not receive the error.

I have the following modules installed:

ACL 6.x-1.0-beta2
Admin Role 6.x-1.0-beta2
Advanced help 6.x-1.1
Content Construction Kit (CCK) 6.x-2.1
Content Access 6.x-1.x-dev (2008-Oct-30)
Date 6.x-2.0-rc5
LDAP integration 6.x-1.0-alpha2
SimpleViews 6.x-1.0
Views 6.x-2.1

Same error. Does this effect the actual assignment of permissions, or is it just complaining? Anyone know? If so, this bug needs to be marked major.

Thanks,

Changed priority to normal until it can be ascertained whether or not permissions assignment using Drupal core permissions is affected.

Same here. No issues as yet. Would be nice to 'understand' why this is happening... fago?

In my experience the problem only occurs when changing permissions by editing a specific role. The code assumes you're coming in via 'permissions' rather than 'roles' but in this case the $form_state['values'] array only has data for the specific role so iterating through all roles causes the warning.

I got rid of the warning by changing the offending line to only check against existing role ids in the $form_state['values'] array:

if (isset($form_state['values'][$rid]) && (in_array($perm, $form['checkboxes'][$rid]['#default_value']) != in_array($perm, $form_state['values'][$rid]))) {

...Ian.

thanks, indeed the code assumed it's the whole permissions page. I've fixed that in 6.x-dev.
