LayoutDefinition

  • has a list of field names composing the layout. Their names match those of the FieldDefinition(s)
  • specifies LayoutProducer implementation class


LayoutProducer

  • is instantiated from a LayoutDefinition
  • createLayout(LayoutDefinition, Map<String, Component>) creates the actual layout (a Vaadin Component) from
    • LayoutDefinition
    • a mapping of field names and actual field components

Form

  • is a plain Java class

  • it stores
    • its Binder
    • its own Layout (including sub-form layouts)
    • its sub-forms
  • can save and validate self and its sub-forms recursively (should this functionality move away from Form?) 

FormPresenter

  • is currently the orchestrator of the form building process
  • creates the final form view (a Vaadin Layout)
    • instantiates a Form from a FormDefinition
    • returns the form view to the caller

    • TODO 

      • set labels, help messages and descriptions: use something like info.magnolia.ui.dialog.formdialog.FormView?

      • update forms/fields based on Locale? See info.magnolia.ui.dialog.formdialog.FormPresenterImpl.updateForm()

      • pass it

    • gets passed

      • to DetailPresenter(..) which takes care of initializing actions and other stuff before calling and setting the form view produced by FormPresenter?
