I'm having accessing my smart contracts' setters from console using a simple HTML / JS website. I'm able to access public variables and getters, but when trying to use my setters from console it throws an "invalid address" error.
Some google'ing told most of the time the reason for this problem is not having set an default address, but I did this in my JS script (web3.eth.DefaultAccount = web3.eth.accounts[0];). Is there something else I've missed?
I'm using the Remix IDE for writing / publishing the smart contracts and connect to my locally hosted testRPC network. I'm trying to use my setter by entering Contract.setter("test") in the console.
error:
