[SCA Java M2] Should Reference multiplicity be working?

[Bert Lamb <al...@pobox.com>]

In looking at the 0.95 Java C&I spec (and it looks to be done the same
way in the draft 1.0 spec) I see that it should be possible to have
multiple references collected up in a list using an annotation such as
the following:

@Reference(name="helloService", required=true)
public List<HelloService> helloServices;

However attempting this gives me the following error:

org.apache.tuscany.spi.builder.BuilderConfigException: Incompatible
source and target interfaces

Should this be working in M2?  Is this broken or is multiplicity per
the spec not supported at this time?

Hi,

I added basic support in the code already a few weeks ago. You can annotate 
the reference like:

@Reference
MyInterface[] refs;

or

@Reference
java.lang.Collection refs;

Thanks,
Raymond

There is also a JIRA around this :

Hi Bert,

It's not supported in M2. This is something I'd like to get in as we  
change over to support federated deployment in the next release. We  
are actively working on some changes to core which will make this  
easier to support, particularly in the autowire case (a new SCA  
feature proposed by Tuscany and accepted as part of the 1.0 specs :-) )

Jim
