Solidity - EVM Webpackアプリ使用時のJUMPが無効

Question

Truffle + Webpackベースのフロントエンドアプリを作成しています。この場合はhttp://truffleframework.com/tutorials/building-testing-frontend-app-truffle-3です.JavaScriptは全くありません。

コードは、トリュフのコンソール上で動作し、アプリがグローバルbuy_orderbook_brent

ソリディティと呼ばれる構造体配列に新しい要素を追加し、機能「append_buy_brent」を除き、動作します：

contract Petroleum{ 


// Initialisations 

address _creator; 
uint user_number; 


struct Baril_order { 
    uint price; 
    uint quantity; 
    address addr; 
} 

Baril_order[] buy_orderbook_brent; 

mapping(address => uint) account_map; 
mapping(uint => uint) user_balance; 
mapping(uint => uint) number_of_brent; 

function Petroleum() payable{  

    _creator=msg.sender; 
    user_number=0; 
    test=0; 

    account_map[_creator]=0; 
    account_map[0x7f8105da4dd1af61da7bf587766103ba8534fcdc]=1; 

    user_balance[account_map[msg.sender]]=100000; 
    number_of_brent[account_map[msg.sender]]=5; 
    number_of_wti[account_map[msg.sender]]=2; 
    debt[account_map[msg.sender]]=20; 
    user_balance[account_map[0x7f8105da4dd1af61da7bf587766103ba8534fcdc]]=200000; 
    number_of_brent[account_map[0x7f8105da4dd1af61da7bf587766103ba8534fcdc]]=7; 
    number_of_wti[account_map[0x7f8105da4dd1af61da7bf587766103ba8534fcdc]]=10; 
    debt[account_map[0x7f8105da4dd1af61da7bf587766103ba8534fcdc]]=3; 
} 

function append_buy_brent(uint price, uint quantity, address addr) payable { 
     buy_orderbook_brent.push(
      Baril_order({ 
       price:price, 
       quantity: quantity, 
       addr: addr, 
      }) 
     ); 
    } 
} 

JavaScriptを：

import { default as Web3} from 'web3'; 
import { default as contract } from 'truffle-contract' 
import Petroleum_artifacts from '../../build/contracts/Petroleum.json' 
var Petroleum = contract(Petroleum_artifacts); 

var accounts; 
var account; 
var account1; 

window.App = { 
start: function() { 
    var self = this; 

    Petroleum.setProvider(web3.currentProvider); 

    web3.eth.getAccounts(function(err, accs) { 
     if (err != null) { 
     alert("There was an error fetching your accounts."); 
     return; 
     } 

     if (accs.length == 0) { 
     alert("Couldn't get any accounts! Make sure your Ethereum client is configured correctly."); 
     return; 
     } 

     accounts = accs; 
     account = accounts[0]; 
     account1 = accounts[1]; 

     self.refreshBalance1(); 
     self.refreshBalance2(); 
    }); 
    }, 

append_buy_brent: function(){ 
     var self = this; 

var price_buy_brent= parseInt(document.getElementById("price_buy_brent").value); 
     var quantity_buy_brent=parseInt(document.getElementById("quantity_buy_brent").value); 

     this.setStatus("Initiating transaction... (please wait)"); 

     var petro; 

     Petroleum.deployed().then(function(instance) { 
      petro = instance; 
      return petro.append_buy_brent(price_buy_brent,quantity_buy_brent, account, {from: account, value: web3.toWei(1000, "ether")}); 
     }).then(function(value) { 
      self.setStatus("Transaction complete!"); 
      self.refreshBalance1(); 
      self.refreshBalance2(); 
     }).catch(function(e) { 
      console.log(e); 
      self.setStatus("Error placing buy_brent; see log."); 
     }); 
    }, 
}

私は十分な情報をここに初めて渡したかったと思います。どうもありがとう。

EVMのバグのようです。契約展開と関数呼び出しの両方を2つの異なるトランザクションに入れないで試してみてください。
