Compiling below code:

pragma solidity ^0.4.2;
contract HelloWorld {
uint public balance;

function Helloworld(){
    balance = 1000;
}

}

truffle(default)> HelloWorld.balance.call()

Error:

This looks like a bug in truffle, please file a bug report there.

I have also encountered the same issue. How did you solve it?

Hi @jeanjluo : You need to use HelloWorld.deployed().balance.call()

I know this is a fairly old thread, but I'm running the same exact code and running into the same problem. HelloWorld.deployed().balance.call() results in the same error; TypeError: Cannot read property 'call' of undefined. Any idea for a work around?

@steveO1234 @rnkhouse @chriseth @jeanjluo

Try This:

HelloWorld.deployed().then(helloworld=> console.log(helloworld.balance.call()))

OR

HelloWorld.deployed().then(function(instance){helloworld=instance})
helloworld.balance.call()

@daljeetv +1 for your answer. Bingo
