What about FIELD:teaserPID:REQ:FALSE ? This will return TRUE if 
teaserPID evaluates to FALSE (i.e. is 0, '' or does not exist).

I think there is enough information in the thread you linked in one of 
your answers to the original question. You can populate the field with a 
custom function using <itemsProcFunc> and retrieve the value of your 
teaserPID using the code in François's answer.
