Does infura support rinkeby event listening

Question

Hi I ran a simple voting example connecting to https://rinkeby.infura.io/ since I do not run local Eth node. Everything works fine except event watching.

var event2 = contractInstance.EventTester(); event2.watch(function(error, result){ if (!error){ console.log(result); }else {console.log(‘ERROR’)} });

When I submit a transaction I do not see that the event was fired (it is called in the contract function). Am I missing anything ?

I have been having horrible problems catching events in Rinkeby test net using Metamask. I know things work because I can use Metamask though localhost (testrpc) and it works fine, but it is extremely intermittent with Metamask.

This seems to be a really common issue. I have solved it by instead logging the tx hash that is returned when you make a tx, and then calling web3.eth.getTransactionReceipt(txhash) until it returns not null, and parsing the events from there.

Hopefully this helps. Of course this isn’t viable in all situations.
