Worker Objects - $completed where?

[Ben Butler]

Hi,

I must be being a bit slow.  With the SQL Worker Objects, where does the 
$completed and $cancelled methods go.  I have put them in the object 
that contains the methods that call $init and $start and they dont get 
called...?  Do they go inside the Worker Object itself, but they are not 
shown in the interface manager for that object variable and how would I 
assign their contents anyway.  The worker object has a status of 
kWorkerStateCompleted after calling $start, but I am a bit of a loss for 
where the call back is going?

TIA

Ben
