selector for empty page reference field

[sujag]

I'm stuck finding the right selector syntax for an empty page reference field.

I can select all pages with template "fest" that have an entry in selectLocation

$oF = $pages->find('template=fest,selectLocation.id>0');

but now I need the contrary. Find all pages with template "fest" and an empty selectLocation 

My selectLocation Field is setup to reference a single page, but all tests with

$oF = $pages->find('template=fest,selectLocation=FALSE'); or 0 or false won't work.

Try: selectLocation.count=0

Thanks, that works
