Hi

I am working on a project for model transformation. I want to use the attribute of one class that is referenced by another
class. Among them, Datatype is a class that includes an attribute (name) and a refference (datatypep), Pattern is another class that
includes two attributes (pattern, constructor) and a refference (patternd), datatypep is the opposite reference for patternd.
but the compiler always show bug. Please help me. Thanks.

The bug:

org.eclipse.m2m.atl.engine.emfvm.VMException
at __initexpressions#125(Enumerative2Function.atl[64:51-64:84])
local variables: self=IN!<unnamed>

The ATL code:

helper context Enumeratives!Pattern def: DatatypeName : String =
if not self.datatypep.oclIsUndefined()
then
self.datatypep.name
else
''
endif;

helper def: FunctionNameProfix : String = 'eval_';

helper context Enumeratives!Pattern def: patterns : String =
if not self.pattern.oclIsUndefined()
then
if self.pattern = 'int'
then 'n'
else if self.pattern = '(' + thisModule.DatatypeName + ')'
then '(e)'
else if self.pattern = '(' + thisModule.DatatypeName + ', ' + thisModule.DatatypeName + ')'
then '(e1, e2)'
else if self.pattern = '(' + thisModule.DatatypeName + ', ' + thisModule.DatatypeName + ', ' + thisModule.DatatypeName + ')'
then '(e1, e2, e3)'
else ''
endif
endif
endif
endif
else
''
endif;

rule P2C {
from
s : Enumeratives!Pattern
to
t : Functions!Clause (
clause <- s.constructor,
pattern <- s.patterns,
expression <- s.expressions
)
}

Best,

Yi
