Hi there,

class Module{ name, address}
class ModuleList{EReference moduleItem of the type Module}

class Model{name, address}
class ModelList{EReference modelItem of the type Model}

problem:

-- @path source=file:/C:/.../Module.ecore
-- @path target=file:/C:/.../Model.ecore

create OUT : target from IN : source;

rule Rule_1{
from
a:source!ModuleList
to
d:target!ModelList(
modelItem.name <- a.moduleItem.name
)

}

Error: no viable alternative at input '.'

Can someone tell me how to resolve this issue? In some other terms, how to use EReferences in ATL programming? Could someone show me a simple example?

Thanks in advance
K

Hi

I think you need a matched rule like the following

rule Module_2_Model {
  from 
    input : source!Module
  to
    output : target!Model (
      name <- input.name,
      address <- input.address
    )
}

So in the bindings of your rule you could write: modelItem <- a.moduleItem
