Well i thought at first that you didn't specify metadata.xml but i see now
that you did. Mixing metadata.xml and annotations for one single component
is a mistake. For same component you must go with one of them.
So there are 2 different ways for you:
1- Using only annotations: Just disable the metadata.xml (easily delete it
or comment out the content ) and leave the annotations as it is.
2- Using only medata.xml: If you want to use metadata.xml then remove all
annotations including @validate and @invalidate and make sure your
metadata.xml looks like this:
<ipojo>
<component className="cook.michael.MyComponentImpl">
<callback transition="validate" method="start"/>
<callback transition="invalidate" method="stop"/>
</component>
<instance component="cook.michael.MyComponentImpl"/>
</ipojo>
Either way should bring you where you want. Just don't mix annotation and
metadata usage for same component.

Gokturk
