@akelad need your help here. Thanks

Could you share the logs of your action server? It seems like it does call your action server to validate the slots

ahhh @noman it’s because you overwrote the `run()` function, which now doesn’t do anything. If you remove it I believe it should work

And you should only need to subclass the `FormValidationAction` so that it’s `class ValidateOrderForm(FormValidationAction)`
The default implementation of the run method is listed [here](https://github.com/RasaHQ/rasa-sdk/blob/master/rasa_sdk/forms.py#L746)

ahan ok but to add custom slot mappings and require extra slots we need to override run function as stated here [Forms](https://rasa.com/docs/rasa/forms#custom-slot-mappings). Then in this case what will we do?

Then you subclass a normal `Action`, and define the validation logic there. You can find an example in Sara, our demo bot, [here](https://github.com/RasaHQ/rasa-demo/blob/rasa-2.0/actions/actions.py#L50) - keeping in mind that the method has been renamed to `tracker.slots_to_validate`. The example is still in process of being updated

In helping you out with this I realise that that implementation isn’t ideal, and the docs are also a little bit confusing! Will talk to our team on how to address this 🙂

ok Thanks. @akelad can i keep using `FormAction` from `rasa_sdk` with rasa==2.0?

hm, i think it’s still gonna work for now, but we will deprecate it eventually. So it’s better to migrate eventually. Are there any particular parts you’re struggling with?

Hmm ok. Right now i was facing the problem in validation, if i face any while exploring rasa==2.0, will ping you. Thanks for the help.

Of course, even after migration, there is a bug in Rasa 2.0 and extracted slots will get again ignored, and the form will ask again for the slots.
Currently there is no way to get this working, we are awaiting for a fix.

@petasis not sure what you mean, as far as I understood your particular issue is with slots from the trigger message. As already mentioned, we’re working on looking into this and will update you when there’s an update. Repeatedly posting about this isn’t going to speed things up.
If you are talking about a different issue than I assumed, then please feel free to open another post so that we can address that separately.

No, I am talking about a different issue, the slots of trigger messages is the bug that makes my bot unusable. I started migration to rasa 2.x on September 28, having a deadline for a demo on October 5. Then I realised that it was not my fault my forms were not working, I updated from rc3 to rc4, found a workround for rc4 on October 7, and on October 8 you released version 2.0. Which changed again how forms should work (from rc4), I updated again my bot, but my forms still do not work, and I cannot find a work around. 7 days later, I still have no solution, no demo, and no plan for a fix from rasa.
What should I do? Go back to 2.0.rc4? Go back to 1.x?
(And if you remember this thread [Rasa 2.0, how are forms working?](http://forum.rasa.com/t/rasa-2-0-how-are-forms-working/35425/5), the problem exists for almost 30 days, and I was hopping 2.0 would fix it - which didn’t -, and the bug has been closed). I really do not know how to proceed.

I’m not sure what you mean, that sounds like the issue I was talking about? The PR submitted that you linked to did fix the issue for our bots. As I asked in the other [thread](http://forum.rasa.com/t/rasa-open-source-2-0-is-out-now/35577/47), it would be great if you can open a _new_ post with all the details related to your issue, since that thread has gotten confusing, with other peoples issues, and also the data being in various different forum posts.
