Eager Loading

Hello Ivy Team,

In my project, I had to switch from the default Eager loading to the Lazy loading of the Entity classes. The reason was that the queries were not optimized. Now I have the following problem, every time I try to inspect the variables in debug mode, the Designer is throwing errors and it is almost impossible for debugging:

Entity Class Migrations

Stelt0 — Wed, 06 Jul 2016 10:08:37 -0400

Hello Guys,

I`m new to Hibernate and JPA. I have an Axon.Ivy project that has couple of Entity Classes. I want to move them in a separate project and separate namespace(package) and also to add some additional fields.

What are the implications when I`m changing the data model and the namespaces ? How do I migrate the changes to the production server ?

In .Net Entity Framework there is a concept of 'migrations' where the changes to the database are applied automatically when the code is deploys.
