You need to add the constant keyword to the test() function like:
pragma solidity ^0.4.0;
contract Test {
mapping (address => uint256) weismap;
function bet(uint vote) payable returns (uint256 weis) {
if (msg.value==0)
throw;
weismap[msg.sender]= msg.value;
return weismap[msg.sender];
}
function test() constant returns (uint myVote) {
return 1;
}
}
Calling bet(...) with the value 2. Note that I'm sending 2 ethers as well with the transaction:
Now I call test() AND I've left the value 2. This call to test() fails as the constant function is being called as a transaction, not a read of the values off the blockchain:
If I call test() AND I've set value to blank, this call to test() succeeds as the constant function is being called as a read of the values off the blockchain:
The problem is that totalSupply() implementation is missing. Seems like autogenerated getters do not count. So you need to explicitly create the function.
contract StandardToken is Token {
uint256 _totalSupply;
function totalSupply() constant returns (uint256 totalSupply) {
totalSupply = _totalSupply;
}
}

When you want to put an element into an array you can use or:
push()method or can specificy the index where this value must be stored like:array[index] = value;.In your smart contract, you must change your method function name because it has the same name of
address[]variable and then you can put the element into array using one of methods that I described you above.Example:
