i made a simple cayenne project with only 2 entities with many - to - many
relationship between: Om - Adresa n:m. i created 3 tables and i used flattened
relation for mapping. the db is mysql 4.1 and cayenne is v1.1. the cayenne
project files are atached
i have 2 jsp : a.jspo inserts values and b.jsp retrieve some
the strange part is i'm inserting 2 values for each entity but i retrieve 3
(where 2 are identical!!).
Example: for the Adresa with id =223 the Om returned are: 225;225;226 !!
a.jsp

o.setNume("gigel");

o1.setNume("gigel");
Adresa a = (Adresa)context.createAndRegisterNewObject(Adresa.class);
a.setAdresa("iuliu maniu");
Adresa a1 = (Adresa)context.createAndRegisterNewObject(Adresa.class);
a1.setAdresa("iuliu maniu");

a.addToOM_ARRAY(o);
