DELETE on JOIN Table happens after I change (append) value to a list

[zenoki...@gmail.com]

Hi Guys,

I have a entity defined like this: 

  case class Instance(

    @Alias("_id") var seId: String,

   @Alias("_keyset") var InstanceKeyset: List[InstanceKeyset]

  )  extends Entity

And I initialised it using this: 

new Instance(seId, List(ks1, ks2))

what I see on the logs on mysql is like this:

INSERT INTO `se_instance` (`_id`, `_keyset`)  VALUES ('96050d3e-d74b-11e4-aebc-3fcfb10387e4-b61bccbc', '1');

INSERT INTO instance_keysets(....)

INSERT INTO instance_keysets(...)

delete from _keyset where owner = ....

insert into _keyset(....

insert into _keyset(....

as you can see, it deletes first all the _keyset row with the given owner and insert two row to establish the linked between Instance and InstanceKeyset.

Is this the proper behaviour?

Thanks,

In addition, even on adding new elements to the list, it did a delete then inserts all elements.
