Let’s first create an enum for our state machine.

[simple-concise-forge]$ java-new-enum --named CatalogueStatus \
  --targetPackage mx.rmm.simpleconcise.forge.model
***SUCCESS*** Enum mx.rmm.simpleconcise.forge.model.CatalogueStatus was created
[CatalogueStatus.java]$ java-new-enum-const \
  --enumClass mx.rmm.simpleconcise.forge.model.CatalogueStatus \
  --named DRAFT
[CatalogueStatus.java]$ java-new-enum-const \
  --enumClass mx.rmm.simpleconcise.forge.model.CatalogueStatus \
  --named PUBLISHED
[CatalogueStatus.java]$ java-new-enum-const \
  --enumClass mx.rmm.simpleconcise.forge.model.CatalogueStatus \
  --named HIDDEN
[CatalogueStatus.java]$ ls
DRAFT      HIDDEN     PUBLISHED  

And add a new field to our existing entity Catalogue

[CatalogueStatus.java]$ cd ..   
[model]$ cd Catalogue.java
[Catalogue.java]$ jpa-new-field --named status \
  --type mx.rmm.simpleconcise.forge.model.CatalogueStatus \
  --enumType STRING 
***SUCCESS*** Field status created
[Catalogue.java]$ scaffold-generate \
  --targets mx.rmm.simpleconcise.forge.model.Catalogue
***SUCCESS*** Scaffold was generated successfully.

Now our user interface looks a little diferent with a new search field and a new column on the table below.

On creation we are propted with a selection box for the enum values.

And everything is ok, right?

But there are problems with our UI, there are no restrictions to values set on fields

Fortunately this can be fixed in a clean way

[Catalogue.java]$ constraint-add --onProperty code --constraint NotNull 
***SUCCESS*** Constraint NotNull successfully configured
[Catalogue.java]$ constraint-add --onProperty description \
  --constraint NotNull
***SUCCESS*** Constraint NotNull successfully configured
[Catalogue.java]$ constraint-add --onProperty status   --constraint NotNull
***SUCCESS*** Constraint NotNull successfully configured
[Catalogue.java]$ scaffold-generate \
  --targets mx.rmm.simpleconcise.forge.model.Catalogue --overwrite
***SUCCESS*** Scaffold was generated successfully.

Metrics

  545 total

  360 total
.xml
 173 total

Our user interface now hints that there are required fields

And there are validations in place for said fields

But still we are missing how to transition in our statemachine within our busines case.

For now let’s continue with sample 02 of our basic UI requirements
