[map] Transformation language not working

[florian-h05]

Expected Behavior

language is used to select transformations based on locales. You could have a transformation "switch" which depending on the locale translated ON to different values. This is also available in file-based transformations by adding a _de suffix to the filename (before the extension).

So if you have foo_en.script and a foo_de.script (or the corresponding managed UIDs), base on the locale either the first or the second is used when you configure SCRIPT(foo.script):%s.

Current Behavior

I have these transformations:

• files
  • switch_de.map
  • switch_en.map
• UI
  • config:map:switch:de
  • config:map:switch:en

Using MAP(switch.map) or MAP(config:map:switch) for Item states does not work and leads to:

Failed transforming the state 'OFF' on item 'test_switch' with pattern 'MAP(switch.map):%s': Could not find configuration 'switch.map' or failed to parse it.

Steps to Reproduce (for Bugs)

See above.

Context

I have discovered this while working on the UI transformation menu & editor.
If this is still supported, the UI needs a minor adjustment for the tip how to use that transformation.
