Getting error when decoding event with indexed fields. #30
Description
Activity
- Okay, so it's possible events here have been altered. I'll take a deeper look tomorrow. Thanks!…Sent from my iPhoneOn May 13, 2018, at 4:41 AM, cryptodungeonsdev ***@***.***> wrote: Hi!

Thanks, would be awesome, this problem doesn't allow to continue some parts of development.
- Yeah, very strange. And have you tried just polling eth getLogs and decoding the results with ethjs abi?…Sent from my iPhoneOn May 14, 2018, at 4:20 AM, cryptodungeonsdev ***@***.***> wrote: Thanks, would be awesome, this problem doesn't allow to continue some parts of development. — You are receiving this because you commented.

No, i will try
Yes, it worked!
- Amazing! I should really make that an easier method for all this…Sent from my iPhoneOn May 14, 2018, at 12:36 PM, cryptodungeonsdev ***@***.***> wrote: Yes, it worked! — You are receiving this because you commented. Reply to this email directly, view it on GitHub, or mute the thread.
That is great, but how to listen for new Logs?
- So, I usually just run a polling loop. Checkout ethjs-extras (a rouge library I wrote) for more details. NPM: https://www.npmjs.com/package/ethjs-extras Github: https://github.com/SilentCicero/ethjs-extras Contract Code: ``` const { Eth, EthContract, onAccount, onReceipt, onBlock, call, } = require('ethjs-extras'); // or import.. // setup a light contract object, use solidity spec and or abi spec. const simpleStore = new EthContract({ network: 'rinkeby', address: ' 0x01a528451419d562a6752318a6fb71898fa5d840', methods: [ 'SimpleStore(address _master)', 'set()', 'Set(uint256 _value)', 'master():(address)', ' get():(uint256)', ], }); // contract methods, promise only simpleStore.get ().then(console.log).catch(console.log); // using shorthand notation simpleStore.master.call().then(console.log).catch(console.log); // using .call() notation simpleStore.onEvent(console.log); // polls for events, receives, decodes and fires callback <-------------------------- simpleStore .getLogs({ fromBlock: 0 }).then(console.log).catch(console.log); ``` Event Polling I do here (every block): https://github.com/SilentCicero/ethjs-extras/blob/master/src/index.js#L190 hope this helps, sorry swamped with work!…On Wed, May 16, 2018 at 2:49 AM, cryptodungeonsdev ***@***.*** > wrote: @SilentCicero <https://github.com/SilentCicero> — You are receiving this because you were mentioned.

Hi! I'm using Ganache 1.0.1 and ethjs 0.4.0.
Here how i use watcher:
I believe this was outlined at https://github.com/ethjs/ethjs-abi/issues/15
But no response at all, i'll try get response here instead.
