[#6401] Auto Action - "Add usergroup" does a "Replace usergroup" instead

I just wanted to add all users that had a specific field set to a Joomla Group, and to my dismay it instead replaced the existing user groups instead of adding one, I did not use Replace Groups, only Add Groups.

Works perfectly fine in my tests and has always worked fine. There's no reason to believe it'd spontaneously stop working. What trigger are you using? Most likely you're overriding an existing user object as CB Auto Actions does not use references by default as you have to specify what variables are references as it can't possibly know in advance per trigger usage. To avoid that you need to either specify the reference variables or enable reload user. Both are configured under the Parameters tab of your auto action.

I have created a very simple rule.
The trigger is users.
The condition is
If cb_rykker EQUAL TO 1
Add usergroup Rykker

I tested it by activating the Users link under the auto action plugging

After that, all the Users that had the cb-field to 1, only had the Rykker as groups.

Was able to confirm your issue for that trigger. For some reason for that trigger the gids array is empty. Unsure why at this time, but have added a bug ticket to investigate further. This issue doesn't seam to affect triggers like after login so I suspect it's a problem with how user objects are built for the internal users trigger.

Ok, have fixed for next build. Should be released later today or early tomorrow. Now uses API to grab the users current usergroups instead of relying on gids variable.

Wow, excellent work, I'll test it out tomorrow then
