Hi all,  
	I've just started playing around with PW and have set up a basic JSON response to return fields in JSON format. 
	I can get basic field data fine, eg. title as strings but I'm having trouble with other field types.
 
	For instance the response for a repeater which has two text fields and an image field is:
 
{"data":"1021,1022,1023","count":3,"parent_id":1020}}
	How can I pull out the content of these inner fields?
 
	Is there a normal pattern custom field types use to reference data?
