Class Family
  Property Name as %String [Required];
  Relationship Category As Category
 [ Cardinality = parent, Inverse = Families];

Class Product
  Property Category as Category [Required];
  Property Family as Family;

I have 2 or more properties Parent-Child related presented as Select Boxes (Drop Down).

For instance:
 Category (the main one) having "Hardware","Software"
 Family having "IBM","HP","Microsoft"

When loading the form, i have all the data load and i can put Microsoft selling Hardware :-( Not a good idea...
My problem is just on loading because OnChange everything is fine.


Any hints ??

TIA
Nuno
