Contract deployment error : value.forEach is not a function

Question

This is a simple contract I am trying out with an Ethereum testrpc instance.

pragma solidity ^0.4.11;
/// @title List

// Begin contract defintion
contract List {

    struct ListMembers {
        bytes32 listOwner;
        bytes32[] members;
        uint256 rNumber;
        uint256 aNumber; 
        uint256 uNumber;  
    }

    ListMembers public lm;
    mapping (bytes32 => bool) public addedMembers;

    function List(bytes32 listOwner) {
        lm.listOwner = listOwner;
        lm.rNumber = 10000;
        lm.aNumber = 0;
        lm.uNumber = 0;
    }
}

And, this is the web3.js code to deploy the contract.

var Web3 = require('web3');
var fs = require('fs');
//
var ethHttpProvider = new Web3.providers.HttpProvider("http://localhost:8545");
var web3 = new Web3(ethHttpProvider);
var abiFile = fs.readFileSync('Lists.abi').toString();
var abiDef = JSON.parse(abiFile);
var byteCode = fs.readFileSync('Lists.bin').toString();
//
var listContract = web3.eth.contract(abiDef);
deployedContract = listContract.new('A',{data: byteCode, from: web3.eth.accounts[0], gas: 4700000});
//

And, this is the error I am getting:

TypeError: value.forEach is not a function

What am I missing?

Answer 1

The correct format is to pass it as an array element as described in wiki. So, it is, listContract.new(['A'],...)
