Magento 2 dynamicRows作为管理员客户编辑的新标签，如何加载数据？

Question

如何将来自Customer DataProvider插件的数据加载到ui_component dynamicRows中？

我已经在admin客户编辑表单中创建了一个新标签，并添加了我的ui_component，看来效果很好。但是我无法填充已经存储在数据库中的数据。

我尝试为DataSource添加xml，但是我认为这与原始的customer_form.xml DataSource“ customer_form.customer_form_data_source”有冲突，因为当我添加DataSource时，该页面不再加载。

数据源XML：

<dataSource name="mycustomrows">
    <argument name="dataProvider" xsi:type="configurableObject">
        <argument name="class" xsi:type="string">MyVendor\MyModule\Model\Customer\DataProvider</argument>
        <argument name="primaryFieldName" xsi:type="string">id</argument>
        <argument name="requestFieldName" xsi:type="string">id</argument>
        <argument name="meta" xsi:type="array">
            <item name="myshipping" xsi:type="array">
                <item name="config" xsi:type="array">
                    <item name="label" xsi:type="string" translate="true">My Custom Rows</item>
                </item>
            </item>
        </argument>
        <argument name="data" xsi:type="array">
            <item name="js_config" xsi:type="array">
                <item name="component" xsi:type="string">Magento_Ui/js/grid/provider</item>
            </item>
        </argument>
    </argument>
    <argument name="data" xsi:type="array">
        <item name="js_config" xsi:type="array">
            <item name="component" xsi:type="string">Magento_Ui/js/form/provider</item>
        </item>
    </argument>
</dataSource>

dataSource的dataProvider：

<?php

namespace MyVendor\MyModule\Model\Customer;

class DataProvider extends \Magento\Ui\DataProvider\AbstractDataProvider
{
   protected $loadedData;
   protected $collectionFactory;

   public function __construct(
       $name,
       $primaryFieldName,
       $requestFieldName,
       \MyVendor\MyModule\Model\ResourceModel\Row\Collection $collection,
       \MyVendor\MyModule\Model\ResourceModel\Row\CollectionFactory $collectionFactory,
       array $meta = [],
       array $data = []
   ) {
       $this->collection = $collection;
       $this->collectionFactory = $collectionFactory;

       parent::__construct($name, $primaryFieldName, $requestFieldName, $meta, $data);
   }

   public function getData()
   {
       if (isset($this->loadedData)) {
           return $this->loadedData;
       }

       $collection = $this->collectionFactory->create(); 
       // add Filter for Customer ID
       //->setOrder('position', 'ASC');
       $items = $collection->getItems();

       foreach ($items as $item) {
           $this->loadedData[$item->getId()] = $item->getData();
       }

       return $this->loadedData;
   }
}

我相信数据必须按照下面的方式使用“ Magento \ Customer \ Model \ Customer \ DataProvider”的插件加载，但似乎无法在加载时填充行。

}

加载客户编辑页面时，似乎看不到任何记录。
