I have three custom post types declared in my functions file, they are all registered in the same way by a function assigned to init with a priority of 1 as below,

add_action('init', 'post_type_xxx',1);

they all work correctly, relevant menus etc are visible and i can add/edit for me as admin since they all use

'capability_type'=>'post'

however two of them are not available within RS, as they do not show in the list of post types on Roles>options>realms

after some experimenting it seems that they will not appear here unless the 'public' meta argument for register post type is true, although it appears i can still override the component values (show_ui, publicly_queryable, exclude_from_search, show_in_nav_menus) individualy to whatever i like to achieve the desired results.

this seems a little odd and unintuitive particularly since the 'public' arguments default value is false.

unless there is some other reason why they would not be appearing?

p.s. following debugging advice from another post i put a print_r of $wp_post_types in the

force_distinct_post_caps() function in role-scoper/wp-cap-helper_cr.php

the dump contained all of my custom post types.

makes perfect sense when you put it like that. thanks for the quick reponse and confirming i wasnt going mad.

perhaps public=false types could at least still appear in the RS interface under Roles>options>realms just not checked by default? perhaps even grouped seperately with an additional warning message? this should not break anything by default, but would give users the option to toggle filtering on without having to set public to true and other flags to whatever is required to actualy preserve their non public functionality which just seems odd.

Great plugin by the way, it is a must-have on most of my wordpress builds with more than a single user/editor.
