SoapUI - How to create dynamic array mock responses for REST call

Thanks

I managed to get this working in the end. I picked up the incoming requests and set them as an array, managed to loop through them and build up a variable containing dynamic responses to each and output the variable as my response. 

Here's my code for anyone interested, not the prettiest but did the job

// Parse the JSON request.
def jsonrequest = new groovy.json.JsonSlurper().parseText(mockRequest.getRequestContent())

// Capture values from request
requestContext.echoOrderCorrelationId = jsonrequest.orderCorrelationId

//Define Incoming Array for CorrelationIds 
def myarray = new ArrayList<String>(requestContext.echoOrderCorrelationId)
def arraysize = myarray.size()

//set variables for use in while loop
def count = 0
String Response = '['
String Full = ''

while(count < arraysize)
{
//take the correlation ID for item in the loop
def CorrelationID = myarray.get(count)
//write the body of the response for the item in the loop
String Body = '{"orderCorrelationId": "' + CorrelationID + '","customerName": "MOCK Customer","responseStatuses": [{"code": "","message": "OK","severity": "INFO"}]}'

//increment the count
count++

//check if last iteration
if (count < arraysize)
{
//add comma to continue adding records
Full = Response + Body + ','
Response = Full
}
else
{
//add ] to finalise response
Full = Response + Body + ']'
Response = Full
}
log.info "Body = ${Response}"
}

//set variable to return for Response Body
requestContext.ResponseBody = Response

For my response I just default to an OK and use ${ResponseBody} to output my variable
