Magnolia CMS 6.2 自定义字段

Question

如何从 JCR 获取 Magnolia 6.2 版自定义字段工厂的项目值？在早期版本的 Magnolia 中，Abstract FieldFactory 实现中是属性 Item 项。从 6.2 版开始。它不再存在。

public class CustomFieldFactory extends AbstractFieldFactory<String, CustomFieldDefinition> {
    @Inject
    public CustomFieldFactory(CustomFieldDefinition definition, ComponentProvider componentProvider) {
        super(definition, componentProvider);
    }

    public Component createFieldComponent() {
        Object field;
        if (((CustomFieldDefinition)this.getDefinition()).getRows() > 1) {
            TextArea textArea = new TextArea();
            textArea.setRows(((SalesVolumeFromDataHubFieldDefinition)this.getDefinition()).getRows());
            field = textArea;
        } else {
            field = new TextField();
        }
  
        if (((CustomFieldDefinition)this.getDefinition()).getMaxLength() != -1) {
            ((AbstractTextField)field).setMaxLength(((CustomFieldDefinition)this.getDefinition()).getMaxLength());
            MaxLengthIndicatorExtension.extend((AbstractTextField)field);
        }

        ((AbstractTextField)field).setPlaceholder(((CustomFieldDefinition)this.getDefinition()).getPlaceholder());
        return (Component)field;
    }
}

Answer 1

您可以将 ValueContext<Node> 注入字段工厂构造函数。然后你可以通过

检索它

Node dialogNode = valueContext.getSingleOrThrow();
Property thisFieldProperty = dialogNode.getProperty(getDefinition().getName());

Here为测试例

Answer 2

@Override
protected GenericButton createFieldComponent() {
    Node node = valueContext.getSingleOrThrow();
    GenericButton button = new GenericButton();
    button.setButtonCaption("Senden");
    button.setVisible(true);
    button.getButton().addClickListener(createButtonClickListener(node));

    return button;
}
