Importing something that does not exists should produce an error message #72

Open GoogleCodeExporter opened 8 years ago

GoogleCodeExporter commented 8 years ago 
What steps will reproduce the problem?
1. Create the following two grammars
abstract A = {}
abstract B = A [ doNotExists ] ** {}

2. run gf B.gf

What is the expected output? What do you see instead?
Expected an error telling me that doNotExists does not exists in A, instead 
everything goes as if there was no problems.

Please provide any additional information below.
The same happens with concrete grammars
