Struggling to render the UI component #8
Description
I have copied the Select example into view/adminhtml/ui_component/select2.xml. In my layout.xml I have added:
<?xml version="1.0" encoding="UTF-8"?>
<form xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:noNamespaceSchemaLocation="urn:magento:module:Magento_Ui:etc/ui_configuration.xsd">
<argument name="data" xsi:type="array">
<item name="options" xsi:type="object">Magento\Customer\Model\Customer\Attribute\Source\Group</item>
<item name="js_config" xsi:type="array">
<item name="dataType" xsi:type="string">text</item>

<item name="maximumSelectionLength" xsi:type="string">1</item>
<item name="tags" xsi:type="string">true</item>
</item>
</item>
</argument>
</form>In my layout file:
<?xml version="1.0"?>
<page xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" layout="admin-2columns-left" xsi:noNamespaceSchemaLocation="urn:magento:framework:View/Layout/etc/page_configuration.xsd">
<body>
<referenceContainer name="left">
<uiComponent name="select2" />
</referenceContainer>
</body>
</page>The output I get is:
Fatal error: Method Magento\Ui\TemplateEngine\Xhtml\Result::__toString() must not throw an exception, caught Error: Call to a member function getRequestFieldName() on null in /app/vendor/magento/module-ui/Component/Wrapper/UiComponent.php on line 0
