Let's have an component declared in switchyard.xml, no matter if it has no or some implementation. If you grab a Camel Java/XML component from Palette and drop it to the component and fill and submit the dialog then following code is written to the component:

<camel:implementation.camel/>

instead of

<camel:implementation.camel>
    <camel:java class="com.example.CamelServiceRoute"/>
</camel:implementation.camel>

It is possible to complete the declaration of implementation by Properties dialog, not by Properties view.
