I'm a newbie of quickfix, wish my question is not so stupid (>_<)

I've been able to logon with the client, but can't figure out the structure yet to send orders.

Two minor changes I spotted that needed fixing:
func (e TradeClient) FromApp(msg quickfix.Message, sessionID quickfix.SessionID) (reject quickfix.MessageRejectError) {
fmt.Println("FromApp: ", msg.String()) //This message is in a FIX Message object. not printable directly yet
return
}

and

func (s logonState) FixMsgIn(session *Session, msg Message) (nextState sessionState) {
msgType := new(fix.StringValue)
if err := msg.Header.GetField(tag.MsgType, msgType); err == nil && msgType.Value == "A" {
if err := session.handleLogon(msg); err != nil {
session.log.OnEvent(err.Error())
return latentState{}
}

    return inSession{}
}

session.log.OnEventf("Invalid Session State: Received Msg %v while waiting for Logon", msg.String())
return latentState{}

}

thanks

Conditionally Required Field Missing (44) on market orders
field 44 is Price so any help would be appreciated

Or even better, a unit test or reproducer.

Expected behavior
A clear and concise description of what you expected to happen.

system information:

• OS: [e.g. Linux]
• Go version [e.g. Go 1.16.5]
• QF/Go Version [e.g. v0.6.0]

Additional context
Add any other context about the problem here.

Is there a Golang example of using user and password? Git history suggests there used to be, but it was removed at some point.

We've been using this happily with v.0.6.0, but in v0.7.0 it has no effect and login never occurs (no error). Our previously working code:

func (e *client) ToAdmin(message *quickfix.Message, sessionID quickfix.SessionID) {
	if msgType, err := message.Header.GetString(tag.MsgType); err == nil && msgType == "A" {
		message.Body.SetBool(tag.ResetSeqNumFlag, true)
		message.Body.SetField(tag.Username, quickfix.FIXString(e.username))
		message.Body.SetField(tag.Password, quickfix.FIXString(e.password))
	}
}

Other examples I can find on the 'net (old StackOverflow questions, QF Java docs etc.) suggest this ought to still work, but it would nice to be sure.

would you accept a PR @cbusbey?

• Allow for the project to be built outside the GOPATH with Go 1.13
• Maintain backwards compatibility for at least Go 1.11

Describe the bug

"Repeating group fields out of order (group 268: template is wrong or delimiter 269 not found: expected 2 groups, but found 1)"

To Reproduce
First, I send a fix message with msgType = V to subscribe to the exchange rate data in both bid and offer directions

Then I successfully received the msgType = W message returned by the bank, and the message has data in both bid and offer directions, and the message is correct

However, when the program runs to "marketdatasnapshotfullrefresh.FromMessage(message)" and parses out the message data of msgType = W, and then calls "marketDataMsg.GetNoMDEntries() ", an error occurs, and the error message is as shown above.

Expected behavior
Logically, there should be no error, and the exchange rate data in both bid and offer directions can be successfully obtained.

system information:

• OS: Mac
• Go version: Go 1.16.5
• QF/Go Version v0.6.0

Additional context
I read the ParseMessage() method of the message. In this method, the message data is directly parsed into the Body field, and the Body is a map data structure. It does not support repeating groups. Is it caused by this?

I need to run a FIX service that allows clients to subscribe to receive market data - no need for order entry, the plan is to pull the orderbook from a db - preferable redis or pg - it would be very helpful to have a market data example. I am working on adding this to some of the existing examples but I keep getting "58=Unsupported Message Type"

Is there an example of component ？

Adding Dockerfiles to the project would allow project managers to publish publicly-available docker images of the examples contained in this project.

• Users requiring one of the examples would not need to clone and build the project, instead, by just running a single docker command a user could boot up an example.
• https://goreleaser.com/ is a good resource, it allows pushing images to docker easily, and would also support publishing homebrew taps and go binaries to the project's release page.
