Updating CB 1.9.1 to 4.0.12 and CBSubs 3.0.0 to 4.1.0

EDIT: Ok, no it is clear. The two plugins for CBSubs I am talking about are custom code. They are not made by joomlapolis. this is my fault, I did not know and just found out. Sorry for that. However, maybe they are useful to you? Maybe you could integrate the code into CBSubs.

CB Auto Actions completely covers that usecase without needing to make and maintain another plugin. See the above initial CB Auto Actions configuration as it will allow you to fire any action you want on the substitution state; including the Usergroups action.

If you still allow me one question: These two plugins were programmed for 3.0.0. Do you have any tipps for me on how to port them? I mean, could I just check if they are still running ok, and if everything is ok, then just use them? Maybe I would need to somehow tell CBsubs they are compatible with it... I guess I can figure out how to do that.

No idea, we didn't write the plugins you're using so I've no clue if it was coded properly. You'll need to contact the developer or review and compare against existing plugins.

Ok, I agree it might be better to use Autoactions for this purpose. Just one question: with the custom integration plugin I was able to do the following:
A user buys a merchandise plan. This merchandise includes 2 years of free membership. This means, when the merchandise was purchased, another plan was activated twice (1+1 year).
Is this solvable with Autoactions? I see how it would work for 1 year, can it also work for 1+1 year?

Yes, CB Auto Actions includes a CB Paid Subscriptions action. You'd first subscribe them then renew them for a double duration or have a separate plan with 2 year duration and subscribe them to that (I recommend this approach).

Ok, I will check the auto action and maybe uninstall the other two plugins.

Question: What happened to the two plugins:
CB Ajax Text Field
DB Lookup field
They don't exist anymore?

CB Ajax Text Field

Replace by CB Core Fields Ajax, which can ajax edit any fieldtype.

DB Lookup field

Replaced by CB Query Field, which provides significantly more query field functionality.

Another problem:

Under CBSubs 3.0.0 I used this code

to get a list of all my plans. Plan display access level settings were taken into account and only those plans were returned, the user had access to. Worked like a charm.

Under CBSubs 4.1 this behaviour seems to have changed? Why?

How can I get only those plans a user has access to?
