Hi Davide,
I do have an annotation with automatic=true. But i would expect it to only work if i did not provide a primary-key myself, i.e. when the primary-key is 0 or null or something. If i provide a key for a record which needs to be updated it should obviously leave it alone. Is that is what is going wrong? If so, is it by design to always overwrite a supplied key instead of filling it...

Hi Jan.
It's not normal that Ammentos is generating new primary keys for saved objects if there is no explicit annotation automatic=true above the primary key field.
The save() mechanism has been working fine for several years... could you paste the piece of code you're working on? You said you are making copies of persistent objects: this could actually cause insert stataments, but...

Hi Davide,
I am already using override, but looking at override... it is using save. I understand your assumption about objects not loaded from the database need to be inserted, but the assumption is not always correct.
Anyway, i used a debugger and somehow if i want to update an old record somewhere during the process it gets a new autogenerated primary key (why?!) and then it is...

Hi jdv145
Ammentos' save() mechanism is based on the assumption that any new object (not loaded from the database) must be inserted to become persistent.
If you need to force updating an already existent object without firstly loading it, take a look at Ammentos.override() method.
Regards
Davide.

I looked into the sourcecode and i noticed the following in the save function
in DatabasePersistor.java.
if (!isLoaded(c, obj)) {
insert(c, obj, conn);
} else {
update(c, obj, conn);
}
If i understand it correctly, an object is inserted when it is not loaded before.
I think this is not always reliable for 1 and maybe 2 reasons.
1) If the...
