This is a basic Grails 3 profile that enables Vaadin8-based development. Requires at least Grails 3.3.0.RC1
grails create-app vaadin --profile me.przepiora.vaadin-grails:web-vaadin8:0.2
The generated app contains a Vaadin UI component grails-app/vaadin/vaadin/VaadinGrailsUI.groovy
If you run the app
./gradlew bootRun
You will be able to see it in:
http://localhost:8080/vaadinui
grails create-app vaadin --profile me.przepiora.vaadin-grails:web-vaadin8:0.3
The generated app contains a Vaadin UI component src/main/groovy/vaadin/VaadinGrailsUI.groovy
If you run the app
./gradlew bootRun
You will be able to see it in:
http://localhost:8080/vaadinUI
Services are injected automatically into Vaadin components. You need annotate them with @Autowired to get them injected into Vaadin components.
I get LazyInitializationException when accessing domain classes associations in my Vaadin compponents
When a Vaadin component calls a Grails service, once the service method completes, the Hibernate session is closed which means that any associations not loaded by the query could lead to a LazyInitializationException due to the closed session.
It is therefore critical that your queries always return the data that is required to render the view. This typically leads to better performing queries anyway and will in fact help you design a better performing application.
