In the context Peter says it, he's right. Like this:
Suppose you have this:
<dependency>
<service interface="org.MyService">
</dependency>
In Phoenix, you can look up the dependency with the key "org.MyService"
OR you can give it a role name:
<dependency>
<role>myservice</role>
<service interface="org.MyService">
</dependency>
and use "myservice" as a lookup key.
What Peter means is that in the case where the role defaulted to the
interface
name, there was no way you could have [] or # in the role. If you had
explicitely
specified a role name, then that will be unchanged. That is, if I had:
<dependency>
<role>myservice#</role>
<service interface="org.MyService">
</dependency>
Then lookup ("myservice#") will *still* give me a MyService interface,
and not a
map, because the dependency is still on an interface and not a map.
1.
<dependency>
<role>myservice#</role>
<service interface="org.MyService">
</dependency>
lookup ("myservice") <ERROR>
lookup ("myservice#") instanceof org.MyService
2.
<dependency>
<role>myservice#</role>
<service interface="org.MyService#">
</dependency>
lookup ("myservice") <ERROR>
lookup ("myservice#") instanceof java.util.Map
3.
<dependency>
<role>myservice</role>
<service interface="org.MyService#">
</dependency>
lookup ("myservice") instanceof java.util.Map
lookup ("myservice#") <ERROR>
