Something Wrong with Democracy

[AurevoirXavier]

Why the standard vote's first param is a bool?

It looks like you are using Vote instead of AccountVote.

And the call needs AccountVote.

That is the UI rendering component - it doesn't render aye + conviction, it only renders the "aye". (It is a limited override only)

I can't vote on my chain. But it was worked a few days ago. https://polkadot.js.org/apps/?rpc=wss://pangolin-rpc.darwinia.network#/democracy

react.01.387c2759.js:2 Uncaught Error: createType(Call):: Call: failed decoding democracy.vote:: Struct: failed on args: {"ref_index":"Compact<u32>","vote":"{\"_enum\":{\"Standard\":\"{\\\"vote\\\":\\\"u8\\\",\\\"balance\\\":\\\"u128\\\"}\",\"Split\":\"{\\\"aye\\\":\\\"u128\\\",\\\"nay\\\":\\\"u128\\\"}\"}}"}:: Struct: failed on vote: {"_enum":{"Standard":"{\"vote\":\"u8\",\"balance\":\"u128\"}","Split":"{\"aye\":\"u128\",\"nay\":\"u128\"}"}}:: Enum(Standard):: Struct: failed on vote: u8:: Assertion failed

I can vote from extrinsic.

I check the democracy pallet, I didn't find any new updates. Why Polkadot's component is different from ours?

In the case of the Substrate-standard AccountVote metadata type path the vote value is aliased to a type that can do the aye + conviction encoding into a single u8 instead of every user having to encode that manually.

It implements the specialized encoding as found in Rust -

/// A number of lock periods, plus a vote, one way or the other.
#[derive(Copy, Clone, Eq, PartialEq, Default, RuntimeDebug, MaxEncodedLen)]
pub struct Vote {
    pub aye: bool,
    pub conviction: Conviction,
}

impl Encode for Vote {
    fn encode_to<T: Output + ?Sized>(&self, output: &mut T) {
        output.push_byte(u8::from(self.conviction) | if self.aye { 0b1000_0000 } else { 0 });
    }
}

Applied wildcard matching on metadata type names in https://github.com/polkadot-js/api/pull/4741 - however this is a dangerous path, so would need to see the impact. (So it may be reverted if it "breaks the world" due to over-zealous matching)
