[Acceleo 3] recursive import not supported [message #649287]

Hi all,

I face problems with the import directive. It doesn't import templates recursively, and so the generation output is not the one expected.
I created a small project to explain that (importbug.zip). There is a basic metamodel, an instance of it and 3 templates.

A concept named 'container' holds references to A concepts. AA and AB concepts inherits from A.

The main template (generate) calls the genA template on A elements hold in the container. The genA template is defined in generateA.mtl. Specializations of the genA template are defined in generateAA.mtl. generate.mtl imports generateA.mtl importing generateAA.mtl itself.

The expected result for the given model (container.xmi) is:

        genA
	genAA
	genAB

but I got

	genA
	genA
	genA

It seems like a bug (or a missing feature), right?

Regards,
Christophe.

Hi Christophe,

Could you show us a small example of your templates ? Because from our point of you it seems to be a simple problem of polymorphism, keep in mind that the type of an element is resolved during the runtime.

Hi Stephane,

The whole project can be downloaded with the link provided in my first message. this is not a polymorphism problem. This sample works fine if you merge the generateA and the generateAA templates.

Christophe.

Hi Christophe,

I'm sorry I didn't see the zip archive before Smile

So, the problem is clearly coming from recursive imports that are not supported and we do not intend to support it (just like in Java).
