Problem

A Forum reader recently asked:

“How is it possible to handle a move event in a loopback driver when there is no association? I’ve read that one should not use associations with the loopback driver and just handle everything in the event transform. As I understand it, I need an association to get a move event – when I do a move, I just get a sync event.”

And here’s the response from Lothar Haeger …

Solution

That’s the easiest way in many cases, but it’s not forbidden to use association on a loopback driver. Actually it seems to be a good idea for what you want to do. You can simply add a subscriber matching policy like this:

<rule>
  <description>Match to self</description>
  <conditions/>
  <actions>
    <do-set-op-association>
      <arg-association>
        <token-src-attr name="GUID"/>
      </arg-association>
    </do-set-op-association>
    <do-add-association>
      <arg-association>
        <token-xpath expression="association/text()"/>
      </arg-association>
    </do-add-association>
  </actions>
</rule>

The loopback driver will behave a lot like any other “ordinary” driver. Don’t forget to add a rule like this as last subscriber command transform, too:

<rule>
  <description>Veto all</description>
    <conditions/>
  <actions>
    <do-veto/>
  </actions>
</rule>
