DataLoop Not Working When Get Request Is Enabled???

Hi,

Ok - I have the following hierarchy

DataSource(Directory) with fileContents Property defined - 3 files containing data on network
POST REST step (posting ${#Datasource#fileContents} property)
Groovy Step (extracting CustRefID property from file)
Properties Step (holds CustRefID property value)
GET REST step (get request with ${#Properties#CustRefID})
Datasource Loop (loops back to POST REST step)

The Datasource Loop works fine when I disable the GET request.  i.e. I have a Datasource (directory) type that points to a directory with multiple files that contain a single line of data.  I have 3 files so the testcase executes 3 times.

HOWEVER - as soon as I ENABLE the GET request, the looping stops working.

I've moved the steps around in the hierarchy a little and I've tried changing the 'TargetStep' on the Datasource loop to anything else but it still doesn't loop according to how many datafiles are in the Datasource directory.

Has anyone any ideas?

I haven't read anything that would indicate why adding in a GET request should stop the loop working..

I've attached my project for clarity and a screenshot so you can see my hierarchy.

As with all my posts - I am very, very grateful for all/any comments/guidance/help!
