    Description

      The current FieldLayoutComponent interface mainly provides this method:

      void init(EditorPropertyDefinition var1, Component var2); 

      This allows to the implementation class to know the affected property. Moreover, through valueContext.get it is also possible to know the main component. For instance, in this example:

      form:
        properties:
          name:
            label: name
            $type: textField
          multi:
            label: multi
            i18n: true
            $type: jcrMultiField
            itemProvider:
              $type: currentItemProvider
            field:
              $type: compositeField
              properties:
                uno:
                  label: uno
                  $type: textField
                dos:
                  label: dos
                  i18n: true
                  $type: textField
                tres:
                  label: tres
                  $type: textField 

      a component implementing FieldLayoutComponent (e.g. ProtectFieldButton) will be created for the following properties: name, multi. Moreover, for each row created in the multi component, a new component will be created for the properties: uno, dos and tres. So if in multi we have 2 rows, 8 components will be created.

      Unfortunately, the UI framework has a limitation so it is not possible to know the real node for complex attributes. For instance, for the previous component, we could have in JCR:

      Then, when the component is created for uno property, it is not possible to know whether it belongs to multi0 or multi1. This limitation prevents implementing LIVECOPY-159.

      We would need some way to link the created component with the real node the property belongs to.
