Ambiguous wire target is not reported as an error
-------------------------------------------------
Key: TUSCANY-4005
URL: https://issues.apache.org/jira/browse/TUSCANY-4005
Project: Tuscany
Issue Type: Bug
Affects Versions: Java-SCA-2.0
Reporter: Greg Dritschler
Priority: Minor
I have a component reference with a target that includes only a component name.
<reference name="xyz" target="MultipleServiceComponent"/>
The target component has multiple services. According to the following text in
the assembly specification, the target component must have one and only one
service with a compatible interface.
1844 If <service-name> is not present, the target component MUST have one and
only
1845 one service with an interface that is a compatible superset of the wire
source's
1845 interface and satisifies the policy requirements of the wire source, and
the SCA
1846 runtime MUST use this service for the wire. [ASM60048]
This implies to me that if there are multiple services with compatible
interfaces, I should get an error. This does not happen. Instead the first
match is taken. It's unclear to me why there needs to be only one match. If
there are multiple matches that satisfy the interface and the policy
requirements, it seems like using any of the matches is just as good.
