public class MultiValueSubChildrenNodeTransformer
extends MultiValueChildrenNodeTransformer

Sub Nodes implementation of Transformer storing and retrieving properties (as PropertysetItem) displayed in MultiField.
Storage strategy:
- root node (relatedFormItem)
-- main child node (nodeName = field name)
--- child node 1 (used to store the first value of the MultiField as a property)
---- property1 (store the first value of the MultiField)
--- child node 2 (used to store the second value of the MultiField as a property)
---- property2 (store the second value of the MultiField)
...
Main child node : field name
Child node name : 20 first char of the related value
Property name : field name

Method Detail

getRootItem

protected info.magnolia.ui.vaadin.integration.jcr.JcrNodeAdapter getRootItem()

Description copied from class: MultiValueChildrenNodeTransformer

Define the root Item used in order to set the SubNodes list.

Overrides:
