Служба Java не может быть вызвана с помощью Acceleo

Question

Я определил пользовательскую метамодель с использованием EMF Ecore, и теперь я пишу проект acceleo для создания надлежащего Java-кода.

Acceleo недостаточно для нескольких случаев использования, в основном ищет модель для определенных элементов и содержит дополнительную информацию для некоторых, поэтому мне нужно вызвать пользовательскую службу Java, и я последовал за поэтапным примером, и я верю Я точно знаю, как написать запрос для вызова службы Java.

Проблема заключается в том, что, когда я называю обслуживание с примитивными параметрами Java это работает гладко, но когда я пишу один с типами мета-модели, которые я получаю следующее сообщение об ошибке:

Любой знает, что это не так?

вот код Java:

public void f(CustomAction c){ 
} 

вот код MTL

[query public f(arg0 : CustomAction) : OclVoid 
    = invoke('converter.services.ActivityServices', 'f(metamodel.CustomAction)', Sequence{arg0.oclAsType(CustomAction)}) /] 

Answer 1

Является ли ваш сервис на самом деле находится в пакете converter.services и сгенерированный класс CustomAction на самом деле находится в пакете " метамодель "?

Кстати, вы должны вызвать

[query public f(arg0 : CustomAction) : OclVoid 
    = invoke('converter.services.ActivityServices', 'f(metamodel.CustomAction)', Sequence{arg0}) /] 

нет необходимости явно привести его к CustomAction, поскольку он объявлен как таковой.
