Bid Number is overriding - Is this valid?

Pre-condition: Launched Peer and chaincode
Issue: Bid numbers are overriding.
Steps to Reproduce:
Run Below commands as is:

1. ./PostUsers
2. ./PostItems
3. ./PostAuctionRequest
4. ./OpenAuctionRequestForBids
5. ./SubmitBids
6. Modify bid price (say 12000 for the last record) again run the ./SubmitBids command

Expected: Application should restrict user not to submit bids with new amount on old bid numbers.

go build art_app.go errors

I setup fabric on vagrant.

I was able to run this command successfully.

cd $GOPATH/src/github.com/hyperledger/fabric
make peer
peer node start --peer-chaincodedev

But getting error in 2nd command:

Using go version go1.7.3 linux/amd64

cd $GOPATH/src/github.com/hyperledger/fabric/auction/art/artchaincode
 go build

Output:

What I am doing wrong here?

`copy.image filename` is creating after executing ./PostAuctionRequest script

copy.image filename is creating after executing ./PostAuctionRequest. Is this valid?

Membership Service Provider (MSP) Manager cannot get msp for chain

Hi,

I try to use the auction example below :
https://github.com/ITPeople-Blockchain/auction
I successfully launch the ordere peer, but the Membership Service Provider (MSP) manager cannot find the msp of the chain.
Some of you already encountered this issue ?

Bidding is happening on Auction ID but not checking the Auction Item

Open an Auction with Auction ID 1111 and Item 1000.. Submit bid with Auction ID 1111 and item 1900.. I could see Bid is successful on Item 1900 which is not on Auction.

go get -v -t ./... github.com/hyperledger/fabric (download) package itpUtils: unrecognized import path "itpUtils" (import path does not begin with hostname)

getting this when trying to install upstream libraries

git clone [email protected]:ITPeople-Blockchain/auction.git

cd /home/stens/src/gopath/src/github.com/ITPeople-Blockchain/auction

go get -v -t ./...
github.com/hyperledger/fabric (download)
package itpUtils: unrecognized import path "itpUtils" (import path does not begin with hostname)

Disable "PutOnAuction" button after AuctionID is generated

Disable "PutOnAuction" button after click on "PutOnAuction".

Click on "PutOnAuction" button from Item Details page - After Auction ID is generated, disable "PutOnAuctionID".
Note: Working as expected after Page Refresh.

info for Development & Sandbox Environments?

Hello - I have Hyperledger Fabric 1.0 installed and am trying to get this demo to work. I'm having an issue and am guessing it might be because I'm missing something in my environment. Both links in the README documentation for setting up "Development Environment" and "Sandbox Environment" are not working. Are they available elsewhere?

Open Auction record is not closing after auction timeout

Issue Description:
Open Auction items are not closing after auction timeout.
Steps to Reproduce:
Pre-Condition: launch Peer and Chaincode

1. Register users and Items
2. Run PostAuctionRequest and OpenAuctionRequestForBids
3. Wait for Bid timeout (Don't submit any bids)
4. After bid timeout, I could see the below error log:

Split chaincode in multiple files

This code is really good thanks.

we can make it more readable spliting the code in multiples files, like this repo: https://github.com/IBM-Blockchain/fabric-boilerplate/tree/master/src/build-chaincode

Which version for fabric ?

The branch:master supports the x86_64-1.0.0-snapshot-8d3275f for hyperledge/fabric ?

GetListOfItemsOnAuc - Function name is misleading

GetListOfItemsOnAuc - Function name is misleading.

Pre-Condition: Launch Peer and Chaincode
Description:

1. Register Users and Items
2. Execute ./OpenAuctionRequestForBids and ./PostAuctionRequest
3. Execute
   $PEER chaincode query -l golang -n mycc -c '{"Function": "GetListOfItemsOnAuc", "Args": ["2016"]}'
   No records displayed after execute the above query. But, we should get list of items available on auction.

Current OwnerID is not changing in GetListOfItemsOnAuc after Transfer an item

Issue Descripton:
Current OwnerID is not changing in GetListOfItemsOnAuc function after Transfer an Item.
Pre-Condition:
Launch Peer and chaincode
Steps to reproduce:
Run below commands:

1. ./PostUsers
2. ./PostItems
3. ./PostAuctionRequest
4. ./TransferItem (Update the script with transferring ownership to other user). Execute below command to know the list of Item details on Auction request
   $PEER chaincode query -l golang -n mycc -c '{"Function": "GetListOfItemsOnAuc", "Args": ["2016"]}'
   and execute $PEER chaincode query -l golang -n mycc -c '{"Function": "GetItem", "Args": ["1000"]}' (edit the script with owner ID)

Actual Result:

Bid time is depending on system time - is that valid?

The invoke of chaincode would be executed on multi validators. The output of time.Now() would not be the same.

    bidTime := time.Now().Format("2006-01-02 15:04:05")

    aBid = Bid{args[0], args[1], args[2], args[3], args[4], args[5], bidTime}
    fmt.Println("CreateBidObject() : Bid Object : ", aBid)
