Error: Assignment to lists with more that one item

[rseay]

I am getting the following error message and am stumped as to what it could mean:
ERROR-300: Transformer error
ERROR MESSAGE: Error evaluating transformer
org.mozilla.javascript.EcmaError: TypeError: Assignment to lists with more that one item is not supported

The channel is supposed to map an MDM message into more than one table. Complete error message is below, and I've attached the current incarnation of the channel.

Re:Error: Assignment to lists with more that one item

This means that you have multiple segments that you are trying to assign to one variable. You must iterate through these segments and put the values from each segment into each map, or reference them using an offset.

Here's an example referencing with an offset if you have two IN1 segments:

channelMap.put("primaryInsurance", msg['IN1'][0]['IN1.1'].toString());
channelMap.put("secondaryInsurance", msg['IN1'][1]['IN1.1'].toString());

Here's an example using a loop to get each segment:

var i = 0;
for(in1 in msg..IN1)
{
channelMap.put("insurance" + i, in1['IN1.1'].toString());
i++;
}

Re:Error: Assignment to lists with more that one item

Is there a way to accomplish either method within the Transformer edit screen?
