Jelastic manifest prepopulation of list values

I am creating a deploy for OpenMage e-commerce here: https://github.com/ProxiBlue/openmage-cluster

In the creation settings dialog, I want to prepopulate the TIMEZONE, LOCALES and CURRENCY from a list generated by a PHP script.

Relevant parts are here:

I pinged Jelastic support and they gave me this format to use to make the prepopulate:

{ "result": 0, "data": { "yourSettingName1": "value1", "yourSettingName2": "value2" } }

however, that only seems to allow population of single value fields, so I end up with OBJECTS in the list selection:

There must obviously be a different format for this, but their docs don;t show what it should be.

Anyone can help me out here?

Solution

There must obviously be a different format for this, but their docs don't show what it should be.

Option "prepopulate" in JPS manifests can be used only to fill simple "Key:Value" pairs, and does not support a list of values.

Instead, for enabling more dynamic changes in prepopulated values, we suggest you use onBeforeInit event.
