How to change the theme of a group

Same support request here...

For the time being it seems that the extent of your theming options with the default spaces installation is to enable the Spaces Design module that will let users define a custom color and logo for a particular space. Actual theme switching might be nice, but seems more of a feature request.

I am interested in this.

I may have found a solution. On lines 26-30 of spaces_og.module (version 6.x-2.0-beta6) you will find:

// Handle theme switching for OG
if ($this->group->og_theme) {
  global $custom_theme;
  $custom_theme = $group->og_theme;
}

It seems to me that
$custom_theme = $group->og_theme;
should be
$custom_theme = $this->group->og_theme;

This indeed seems to work for me. Additionally, the 'Theme Configuration' for a group is hidden on line 773 _spaces_og_make_hidden($form['themes']);
commenting this out seems to work. Perhaps this is only disabled because the theme switching was not working?

Can anyone confirm that this is a sensible patch?

are you saying unhide what is on line 773?

Edit: for those of us still on spaces 2, do you recommend that we unhide what's on line 773

Thank you. Committed to 3.x: http://drupal.org/cvs?commit=326880

Yes.
The Line
_spaces_og_make_hidden($form['themes']);
Hides the theme selection on the organic groups form, commenting this out, or removing it will allow it to show.
But the actual theme switching won't work unless you fix the other part too.

Thanks Young.

@dylan.riordan, have you actually been able to change themes for the og? I am not able to

I tried spaces 3 beta 2 and I am not able to change the theme

by default it says:
don't switch this them is selected by default
when I select another, the page saves but no theme changes are there
when I go back to the the group edit page and select them configuration for this node, the selection is set back to the default

This is working for me in the latest Spaces dev. Let me know if you have further issues.

yahn, are you saying beta2 or beta3?
