[equinox-dev] service elements in Declaratice Services

["Toedter, Kai" <kai.toedter@xxxxxxxxxxx>]

Hi All,

I currently prototype a little Equinox app that uses Declarative Services (DS). The DS spec 4.1 says "The service element is optional. ... The service element must have one or more provide elements that define the service interfaces". So, the following XML is syntactically correct and handled well by Equinox DS:

<component name="com.siemens.ct.pm.ui.views.treeView">
    <implementation
        class="com.siemens.ct.pm.ui.views.treeview.TreeView"/>
    <service>
        <provide
            interface="com.siemens.ct.pm.application.service.IViewContribution"/>
        <provide
            interface="com.siemens.ct.pm.model.IPersonListener"/>
    </service>
</component>

However, the following XML is incorrect with regards to the DS spec...

<component name="com.siemens.ct.pm.ui.views.treeView">
    <implementation
        class="com.siemens.ct.pm.ui.views.treeview.TreeView"/>
    <service>
        <provide
            interface="com.siemens.ct.pm.application.service.IViewContribution"/>
    </service>
    <service>
        <provide
            interface="com.siemens.ct.pm.model.IPersonListener"/>
    </service>
</component>

... but Equinox handles it exactly like the above correct XML :)

Now the question is, is this a bug or a feature?
If it is a bug, I can file it...
...but how should Equinox DS react then?

Best regards,

Kai
