Hi all.

Is it possible to use a scripted parameter in a workspace to populate the items for a choice parameter ?

So far I’ve had to manually edit the choice list whenever new items needed to be added, but potentially it’s possible to create all the items automatically with a query to a database. This would release me from having to update it manually.

The example I’ve found only talks about returning a single text, but a choice parameter needs a list of display+value pairs.

Any insight is welcome.

Cheers

Kinda - something i’ve been exploring (when i’ve had time!)

You will need to create a transformer (not a custom transformer) using the SDK. In 2024 onwards you can have a dynamic scripted selection populate by python - https://docs.safe.com/fme/html/fpkg-sdk/advanced/scripted-selection/

You might be interested in a new undocumented FME Flow feature present in 2025.1 beta b25583 :

I’ll look into it.

Thanks ​@alexbiz 

Our servers are still 2022, so I’ll need to defer this to when they’re being upgraded.

But thanks for the heads-up.
