You cannot use "->" because it is only for collections:
  - "COMPONENTMETA!Component" is not a collection, it is a single
    element which represents the COMPONENTMETA!Component type
  - allInstances & allInstancesFrom are not operations on collections

You must write:
  COMPONENTMETA!Component.allInstances()
  COMPONENTMETA!Component.allInstancesFrom('InputModelName')


D'oh! Yes of course. Fixed that. However, that does not solve the problem.

Are you using the standard VM or the new EMF VM?


I assume you are referring to the run dialog setting
	ATL Virtual Machine = (Regular VM | EMF specific VM)
I tried both. Does not solve the problem.

In both cases I get something like
  An internal error occurred during: "Launching generateComponentModel".
  operation not found: COMPONENTMETA!Component.From

Any hints?

Would it help if I attach some files from my project?

Thanks for your help,
Goetz

-- here I would like to define the isVisible() function based on the helper variables -- allComponents, allSettings, and allSettingComponentMappings -- however these are all empty true ;
