Hey Денис,
This forum is meant for discussion of the platform and not for technical support. You should post to
Stack Overflow with a more clear explanation of your issue and the users there will be happy to assist you. We monitor our tags on Stack Overflow as well. I'd suggest mentioning:
1. What you expect to see
2. What you see instead
3. Details about how you've written / configured your app
Cheers,
Nick
