Split Batch by Javascript with TCP as source only works when sending as test message within channel.

[AgnerSantiago]

I am not sure what I'm missing or doing wrong, but I have Java script setup for splitting a batch of HL7 messages. The channel is setup as such;

Mirth 4.5.2 version

Data Types
Inbound HL7 v2.x
*Evertying is default execpt Batch
Batch
Split Batch By = Javascript
Javascript has code which splits on a set of lines (code is valid and "works")

Source TCP Listener MLLP
Process Batch = yes
Batch Response = Last
Mode Server

The scenario I'm seeing is. If I go to the channel dashboard and manually send a message there. The splitting successfully happens and I get all the split individual messages.

If I however send the message via the tcp port, the splitting is bypassed completely and all I see is the large batch message.

• I even tried a simple logger info line(like below) and that doesn't even work.
  var line = reader.readLine()
  logger.info(line);
  return '';

Where is the JS code? Post it here. Please use code formatting and syntax highlighting.

The code is located in the Summary > Data Types > Set Data Types > Batch > Javascript

var splitSegment = 'ORC';
var splitPrefix = splitSegment + '|';

var line;
var group = [];

if (globalChannelMap.get('msh') == null) {

    while ((line = reader.readLine()) != null) {
        if (line.startsWith('MSH|')) {
            globalChannelMap.put('msh', line);
            break;
        }
    }
}

var msh = globalChannelMap.get('msh');

if (globalChannelMap.get('pendingLine') != null) {
    group.push(globalChannelMap.get('pendingLine'));
    globalChannelMap.remove('pendingLine');
}

while ((line = reader.readLine()) != null) {

    if (line.startsWith(splitPrefix)) {

        if (group.length > 0) {

            globalChannelMap.put('pendingLine', line);

            var message = msh + '\r' + group.join('\r') + '\r';
            return message;
        }

        group.push(line);
        continue;
    }

    if (group.length > 0) {
        group.push(line);
    }
}


if (group.length > 0) {
    globalChannelMap.remove('msh');
    return msh + '\r' + group.join('\r') + '\r';
}

globalChannelMap.remove('msh');
return '';

I've been using this for testing
