Ceylon's enumerated classes don't work well with Hibernate's default conversion paths. We should see if we can make a ProductType class and a reusable converter.

An example using WebFlux with RouterFunctions could be a great addition. It does not seem to directly translate into Ceylon.

The form-controls-fragments branch modifies productForm.html to use fragments, which makes that file much shorter and simpler. Unfortunately, this also makes that template much less natural, because Layout.js only processes the layout fragment. We should be able to expand the JavaScript functionality to process the new form controls fragment.

The Thymol library exists, but explicitly targets Thymeleaf 2.1, so it might not work for us.

The Entity.dateCreated attribute is supposed to be set once and never update again, but it currently updates every time an entity is saved.

It would be nice to be able to use the ceylon.time module for things like date and timestamp columns and give Spring/Hibernate/JPA/Thymeleaf the ability to translate to and from the Ceylon values. The values should be able to translate to and from the database and be used in HTML inputs via the data-th-field support Thymeleaf-Spring provides.

Currently, only Eclipse can compile the code successfully, because its compiler jumps through extra hoops to avoid "name clash" errors in CeylonRepository and CeylonRepositoryImpl. The Java 9 compiler might work, but we should see if we can get Java 8 to compile this code, because we probably need to wait for Ceylon 1.4 in order to use Java 9.

The "Sign Out" link currently does a GET, which isn't quite right and necessitates CSRF protection being disabled. We should change it into a button that POSTs a form. We then either need to style the button to look like a link or style the "Sign In" link to look like a button.

The User and Role classes each have fields annotated manyToMany. These fields use java.util collections, because Hibernate (and Spring?) does not know how to handle Ceylon collections by default. We should see if we can make a converter for ceylon.lang::List (or even ceylon.lang::Iterable).
