How to store array in capabilities.json object?

[Anonymous]

Hi,

I want to store some values as an array in the capabilitis.json object, The initial value will be null, as based on user interaction I'm updating property value using persistProperties. 

Currently, I declare object type as text, and store array values by converting them to comma-separated values (eg; "val1, val2, val3"). But is there any better way to store array value in settings?

Hi @dm-p,

Thanks for the solution, I also tried diffrent approaches but ended up using the way you suggested.

Hi @Anonymous,

There's no support for complex types as property values. Most developers will use text as the data type (as you're already doing), hide the property during enumeration and JSON.stringify the array before it's persisted. Use JSON.parse when you read it back.

You may be better with the property default as "[]" so that an 'empty' property will parse to an empty array and be ready to work with in your code (or you could coalesce a default null property value to an empty array).
