The signTransaction method does not work correctly.

Input:
oTX:
{
"to": "0xed32e0fd016810B7d3606e1Ae163B58266c544B0",
"gasLimit": "0xc350",
"value": "0x2386f26fc10000",
"chainId": "0x01",
"gasPrice": "0x4a817c800",
"nonce": "0x4"
};
var key = "9cb1 ... 2a84";

Method 1 - OK:
var _key = new Buffer(key, 'hex');
var _tx = new TX(tx);
_tx.sign(_key);

var _raw = _tx.serialize();
var _rr = '0x' + _raw.toString('hex');

:: HASH1 = '0xf86b ... 25a00b3b ... 7f39';

Method 2 - ERR:
web3.eth.signTransaction(tx, key).then(trans);

:: HASH2 = '0xf86b ... 25a009fd ... 08b5';

And the description of the method signTransaction in the documentation does not correspond to the actual result.

I had the same error as in #1986 when using signTransaction. Rolling back to "web3": "1.0.0-beta.34" fixed it for me.

I have also just verified this problem - it seems that chainId is not being properly encoded. In my case, I'm using a private network with chainId of 4 decimal digits, which seems to be causing the issue. When using ethereumjs-tx to sign and RLP encode identical arguments, the tx sends successfully.

Rolling back to "web3": "1.0.0-beta.37" fixes this issue.
