I am not sure exactly what it is that you are trying to achieve. You basically
want to have entities persist themselves(curRole.save())? How do you for

Is there such thing as select distinct in cayenne? I would like to remove
duplicate objects based on a specific column. What is the best way to do it in
cayenne?
Should I have to filter them in memory or is there another way?
Thanks

I have two questions:
1 - What does toDependentPK means?
2 - I would like to use a column of type String as PK. What primary key

Thx.
It seems toDependentPk has to do with mandatory inverse relationship.
I will keep on writing some tests.

Hello,
I have an entity with an attribute description of type BLOB but is
represented in java as a java.lang.String. while trying to save that entity, I
get this error:
org.h2.jdbc.jdbcsqlexception hexadecimal string with odd number of characters
Any Idea?
String - CLOB is working
String - BLOB not so much.

I haven't used H2 without schemas.
Normally I work using this:

I don't know why he is searching for cayenne.xml instead of

My Fault;
I still had this line in my application:
