While calling fallable from Fallback Contract I got Contract trapped during execution. Why MainContract::inc: NotCallable' isn't callable.

@123OLi did you deploy the main contract? Is the account you are calling indeed the main contract's account id?

Yes, I have deployed main contract as well and while deploying fallable contract I indeed choose main contract's account id.

@123OLi but actually you can't just set the callee as AccountId for fallback contract, because as you can see, inside of contract it's type is MainContractRef, anyway that's a good point to change the way it works, so everybody could test it on-chain

@Artemka374 I set the callee as Main Contract

@123OLi but it is still AccountId, you can see the type of variable in UI. Also, I've changed the way contracts are deployed and added README, so you can use guide from there. But if you try to just call fallback as you described previously, it won't work, because reentrancy will occur in fallback contract, which is not allowed, so you can try to just call main contract first, and then you will be able to call fallback method directly.
