[jira] Commented: (ARIES-288) reference in argument doesn't work

    [ https://issues.apache.org/jira/browse/ARIES-288?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12858109#action_12858109 ] 

Valentin Mahrwald commented on ARIES-288:
-----------------------------------------

I have tried to reproduce the problem and failed :( The following worked for me

    <bean id="serviceArgBean" class="org.apache.aries.blueprint.sample.ServiceArgBean" activation="eager"
      init-method="start" destroy-method="stop">
      <argument>
        <reference interface="org.osgi.service.packageadmin.PackageAdmin" />
      </argument>
    </bean>

It also worked when replacing PackageAdmin with a custom service and making sure it only becomes available after the blueprint. 

Have you got a stack trace for when it fails? And where is the service registered in the same bundle or (in)dependent bundle ?
