[Ethereum] Mist: “No data is deployed on the contract address!”

contract-debuggingmist

I'm testing a contract on testnet using Mist.

When I deploy it, it says "No data is deployed on the contract address!".

And then it doesn't appear on the contracts section.

What does it mean?

This happens if the transaction with your contract was mined, but them the wallet couldn't find data on this address using web3.eth.getCode(address). This happens if you don't provide enough gas for storing the contract. E.g. it was executed but not stored. This is an encase and shouldn't happen normally.

[Ethereum] What does “intrinsic gas too low” mean

The intrinsic gas for a transaction is the amount of gas that the transaction uses before any code runs. It is a constant “transaction fee” (currently 21000 gas) plus a fee for every byte of data supplied with the transaction (4 gas for a zero byte, 68 gas for non-zeros). These constants are all currently defined for geth in params/protocol_params.go. Presumably they are also coded into the source for the other node/client implementations as well.

You need to add a transaction object to tell geth what account to use for the transaction:

MyContractInstance.submitUnits('10', {from: eth.accounts[0], gas:3000000});
