Deploying a modified chaincode

I followed this guide

https://github.com/hyperledger/fabric/blob/master/docs/dev-setup/devnet-setup.md

I deployed the chaincode as the command

CORE_PEER_ADDRESS=172.17.0.2:30303 ./peer chaincode deploy -p github.com/hyperledger/fabric/examples/chaincode/go/chaincode_example02 -c '{"Function":"init", "Args": ["a","100", "b", "200"]}'

It worked normally.

Then I modified the chaincode and re-deployed.

But I didn’t see this change impacting on validating peers.

Who could give me some ideas about this problem?

When you say modified the chaincode and redeployed, did you also build the peer image (by doing "go test -run BuildImage_Peer" in the container directory) and restart the peers ?

In fact before you do that, its good to check if the changes were good by testing in "--peer-chaincodedev" mode. Once you did that, do remove the chaincode executable from the source directory (its transient and needed only for dev mode).

If it still does not work, we'd need logs.
