How can i build a JSON output with (multiple) loops?

[bluexblue]

I'm trying to build a JSON output with more than 1 loop. i was able to build an XML using the 'append' feature of tFileOutputMSXML but couldn't find something similar for JSON.

As the snapshot shows, i can only loop on address but not on communications at the same time.

The tWriteJsonField component seems a little lacking on features while working with complex json objects. I have tried using a custom Talend Component "tJSONDoc" ( https://github.com/jlolling/talendcomp_tJSONDoc)

The documentation can be a little confusing in the beginning. If you want to post more info on the intended output structure and what you were able to come up with, please share here.

PS: I am still learning this component, and so far, I have had multiple success overall using this component in creating complex objects.

Thank you for the custom component. I've seen it before but i thought maybe Talend can do it without having to go into installing something external.

Will try to post the end flow when im done..
