# Feature: #82426 - New navigation module registration (e.g. Page tree) {#feature-82426-new-navigation-module-registration-e-g-page-tree}

See [forge#82426](https://forge.typo3.org/issues/82426)

## Description {#description}

When registering an extensions's BE module with `ExtensionUtility::registerModule()` it is possible
to define 'navigationComponentId'.

Before, the 'navigationComponentId' has been used to pass a name of the ExtJS module registered with
`ExtensionManagementUtility::addNavigationComponent()`.

Now it should contain a RequireJS module name. No additional registration is necessary.
The TYPO3 page tree navigation component name 'typo3-pagetree' will still work (thanks to the BC layer)
but will throw a deprecation notice.

Should be changed to new configuration:

```php
\TYPO3\CMS\Extbase\Utility\ExtensionUtility::registerModule(
    'TYPO3.CMS.Workspaces',
    'web',
    'workspaces',
    'before:info',
    [
        // An array holding the controller-action-combinations that are accessible
        'Review' => 'index,fullIndex,singleIndex',
        'Preview' => 'index,newPage'
    ],
    [
        'access' => 'user,group',
        'icon' => 'EXT:workspaces/Resources/Public/Icons/module-workspaces.svg',
        'labels' => 'LLL:EXT:workspaces/Resources/Private/Language/locallang_mod.xlf',
        'navigationComponentId' => 'TYPO3/CMS/Backend/PageTree/PageTreeElement'
    ]
);
```
