It turned out that the ProSyst implementation of Declarative Services
threw an exception if there was a bind method and no unbind method. I
think this is wrong, but I was not up for a fight about it so I added
the unbind method. I'll update the documentation to reflect this.
I find it is no real problem to not implement the unbind method even
though it is i the XML file.
Kind regards,
Peter Kriens
SEH> The BND documentation¹ states that a Service-Component reference with a
SEH> lowercase name provokes a bean-style "set" method to be mentioned in
SEH> the generated XML resource:
SEH> ,----[ Service-Component Header section ]
SEH> | In that case the reference is augmented with a set<Name> method
SEH> | according to the standard bean rules. An unset<Name> method is added
SEH> | when the name appears in the list that is given to the dynamic
SEH> | directive.
SEH> `----
SEH> Note the second sentence, which says that a corresponding "unset"
SEH> method will be mentioned if the reference is noted as being of
SEH> "dynamic" policy.
SEH> Later the document states that the default policy is "static":
SEH> ,----
SEH> | The defaults are therefore aligned with the SCR: a cardinality of
SEH> | 1..1, and static policy.
SEH> `----
SEH> However, I notice that with a maven-bundle-plugin directive like this:
SEH> <Service-Component>com.foo.impl.BarImpl;
SEH> provide:=com.foo.Bar;
SEH> quux=com.foo.Quux</Service-Component>
SEH> The resulting OSGI-INF/com.foo.impl.BarImpl.xml file contains a
SEH> "reference" element like so:
SEH> <reference name='quux'
SEH> interface='com.foo.Quux'
SEH> bind='setQuux'
SEH> unbind='unsetQuux'/>
SEH> Note the presence of the "unbind" attribute. This conflicts with the
SEH> documentation above that states that the unbind method will only be
SEH> mentioned for "dynamic" policies.
SEH> Am I missing something, or is this a bug in BND?
