The correct bug fix would be to use "TreeGenContext". This bug is a copy-paste issue when I tried to fix all places which where missing def procedure_call(self: behav.ProcedureCall, context: TransformerContext):.

behav.ProcedureCall vs. behav.Callable is actually the problem I have mentione don Friday. Only defining one of them can lead to flaky behavior because un-overriden methods will be whatever was defined in the previous transform...

@jokap11 Maybe you could look into

M2-ISA-R/m2isar/metamodel/__init__.py

Line 40 in b54964d

def patch_model(module):

to find a way which resets all generate functions to a default (no-op) visitor, to avoid this kind of issue.

Yeah you are right regarding the TreeGenContext.
I tried to fix the patch_model "monkey_patching" with another branch #67
