hello,

I have the image of the metamodel. I want to get the size of books in the graphic but I didn't succeed

aql:self.eResource().getContents().eAllContents(library:Book)->size()

Thank you for helping

Hi Sarah,

I see a first error in your expression: the type must be written as this: library::Book (you wrote only a single ':').
From where do you call your expression ? If you already are on a Library, you could just use aql:self.books -> size()

Note that you can find the AQL documentation here: https://www.eclipse.org/acceleo/documentation/

Regards,

Maxime
