Sorry, it is possible that I missunderstood your relations.

table: t12
field1: xxx VObjectPtr.t1, kv_Cascade
field2: xxx VObjectPtr.t2, kv_Nullable or kv_Cascade

table: t1

table: t2

this is my understanding of your description.

In both solutions (field2 is kv_Nullable or kv_Cascade) when you now 
delete t1 then the records in t12 should be deleted too, but in t2 
nothing should be deleted or could you explain what your relations 
between the 3 tables?

bye
