Determining the current record is easy. All that is required is to access it using the delegate's own 'index' value, as shown here:
delegate: Text {
height: 30
text: aDocument.contents.hello[index].value
}
Remember that when the entries were created the sub-field was 'value'. So where index = 0, 'aDocument.contents.hello[0].value' will produce '99 Hello Worlds on the wall...!'. Each entry in the document will in turn create its own delegate with a new index number, which can then be used to extract the 'value' (or whatever other sub-field has been created).
