将参数作为字节32传递给Solidity Smart Contract

Question

I am using this Ethereum Go Client and trying to pass a string / bytes32 to Solidity.

The function in the smart contract is very simple (for testing now):

  function vote(bytes32 id) {
    //id has the value 0x0000000000000000000000000000000000000000000000000000000000000000
  }

calling

hash, err := contract.Send(transaction, "vote", "myString")

will result in 0x0000000000000000000000000000000000000000000000000000000000000000

for the bytes32 param id...

How would I have to pass in the parameter to my Smart Contract from Go so that solidity will have the correct value?

Alternatively I just need to pass a unique identifier for that string that I can easily create in Golang from the string...

The creator of the package told me that the reason for this is this issue: https://github.com/regcostajr/go-web3/issues/31

He is trying to solve it.
