nice workaround, but there should of course still be builtin way to 
achieve this. IIRC there where some changes in that area after 1.2.0, 
but I'm not entirely sure.

What would be the suggested way/behavior in your eyes. Which value 
should trigger the deletion? I think '' and 0 shouldn't alter the 
relation, but maybe a -1 could indicate a deletion? Does anybody know 
how this is done in FLOW3?
