I'd like to create a component (dropdown or checkbox), to switch between two data models (let's call them "test", and "prod"), that have the same structure but contain different data.

I tried two ways:

1. A runtime variable called "dm" holding the data model variable name. I used this in the knowledge model like this: dataModelId: §{{dm}}
2. A runtime variable holding a boolean value (1 or 0) called "useProd". I used this like follows: dataModelId: §{{useProd==1?prod:test}}

Both ways didn't work. Did I just do it wrong or is it impossible?
