[jira] Commented: (FELIX-832) Bind method not invoked when the unbind method is unspecified after reference is changed

["Joao Assuncao (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/FELIX-832?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12651757#action_12651757 ] 

Joao Assuncao commented on FELIX-832:
-------------------------------------

This seems to occur because DependencyManager.ungetService(...) is invoked in DependencyManager.invokeUnbindMethod(...). In the situation where unbind is undefined, the reference isn't removed from the list of bound services, and because of that, serviceAdded(...) will find the service still bound and will not invoke the bind method.
The following change seems to fix this problem:
...
if ( m_dependencyMetadata.getUnbind() != null )
{
  invokeUnbindMethod( instance, reference );
}
+ungetService( reference );
...

>          Issue Type: Bug
>          Components: Declarative Services (SCR)
>    Affects Versions: scr-1.0.6
>         Environment: Felix 1.2.1
>            Reporter: Joao Assuncao
>            Priority: Minor
>
> I have a declarative service with a dynamic reference with cardinality 0..1, and since I'm not interested in the unbind notification I did not specified the unbind method.
> I noticed that Felix (1.2.1) invokes the bind method the first time, but it does not invoke it when the reference is changed. After I add a unbind method it works as expected.
