If this abort() is unexpected, build with -s ASSERTIONS=1 which can give more in

Hi,
Thanks for upgrade to truffle version 2.0.4, I have copied the latest version of your code and 'truffle compile' 'truffle migrate' 'truffle test' are all working properly, but only when after issuing 'truffle serve', the page can not load the organizer and buyer address automatically, the earlier version will load contract address, organizer..., could you suggest if it can work in new version?

You need to add an empty images folder to the app folder i.e.
..app/images
Also in Migrations.sol in the contracts folder add a ; at the end of line 8 so it reads:
if (msg.sender == owner) _;

Also add: pragma solidity ^0.4.2; to the start of Conference.sol and Migrations.sol

And now one that had me stumped change line 19 (it will be line 18) unless you add the pragma line to:
function buyTicket() payable public {
That is add the payable modifier to the buyTicket() function. if you don't it will throw invalid jump!
And truffle test will fail.

Still having issues with the refund function specifically
the recipient.send(amount); line.

This project template is set up in Board View with columns and three Asana-created custom fields to help you track your team’s sprint plans. Most teams make projects at the beginning of each sprint and track their work through each stage to make sure they know where their sprint work stands.

We’ve provided some example content in this template to get you started, but you should add tasks, change task names, add more custom fields, and change any other info to make this project your own. When you’re ready to begin work, you can complete this task, or keep it in your project for easy access to our tips below.

Hi, I am getting this error on "truffle compile"

What should I do to fix this?

Uncaught ReferenceError: web3 is not defined at window.onload (app.js:177)

in (app.js:177) code is
web3.eth.getAccounts(function(err, accs) {

With Truffle 2.0.7, I am trying to compile MyConference.sol. I get this error.
Any recent change on Solidity affecting this code ?

This is an example task for you to see how a “real” task in this project works.

Goal: Based on research, we’ve found the top 3 blockers to using calendar and are implementing solutions to solve: discoverability, speed, and functionality.
Metrics: 30% higher calendar usage after 90 days.

I got an error :

I am trying to follow the tutorial you posted on Medium. You linked this repo.

The third-step for deploying a smart contract is add the contract name to "contracts" in config/app.json

But I am using Truffle version 2.0.1 and truffle init does not create a 'config' directory in my project directory.

Hi,

truffle test and serve work

but I get the following error on the console when I go on the browser localhost:8080.

TypeError: undefined is not an object (evaluating 'accounts')
onload — app.js:43735

The contract deployed at: does not show anything too. I'm not sure what might be wrong

I got this error.

thank you for help

Did anyone try running the App?
How can you tell if it is working? I entered a buyer address, clicked on "Buy Ticket".
Registrants number did not change. Clicked on 'Check Balance, nothing happen!
Tried the 'Create Wallet", nothing happen.
The Fund wallet seems to create gas and a transaction but cannot check my wallet balance!
Thanks for your help.

How to fix it?

I am having a compile error when running truffle compile (latest node, python 2.7, all according to instructions):

Migrations.sol:7:3: Error: Expected token Semicolon got 'RBrace'

➜ app git:(master) truffle compile

Compiling Conference.sol...

Compilation failed. See above.

• Boundless
• Dakota Cartography
• North River Geographics?

I had some troubles setting up the project. I dockerize it and put some further instructions.

You can check it here https://github.com/MiguelBel/conference

For bringing up the project just follow the "using docker" instructions.

Feel free to reach me out if you have any trouble with this.
