TYPO3 Core

Hey there,

i have a problem with a extbase/fluid extension with a backend module. In 6.2 works all fine, in 7.1 not. I have the following constants:

module.tx_layerslider {
    view {
        # cat=module.tx_layerslider/file; type=string; label=Path to template root (BE)
        templateRootPath = EXT:layerslider/Resources/Private/Backend/Templates/
        # cat=module.tx_layerslider/file; type=string; label=Path to template partials (BE)
        partialRootPath = EXT:layerslider/Resources/Private/Backend/Partials/
        # cat=module.tx_layerslider/file; type=string; label=Path to template layouts (BE)
        layoutRootPath = EXT:layerslider/Resources/Private/Backend/Layouts/
    }
}

and this setup:

 # Module configuration
module.tx_layerslider {
    persistence {
        storagePid = {$plugin.tx_layerslider.persistence.storagePid}
    }
    view {
        templateRootPath = {$module.tx_layerslider.view.templateRootPath}
        partialRootPath = {$module.tx_layerslider.view.partialRootPath}
        layoutRootPath = {$module.tx_layerslider.view.layoutRootPath}
    }
    settings < plugin.tx_layerslider.settings
    settings {
        tsIncluded = 1
    }
}

In ext_tables.php the module was registered:

if (TYPO3_MODE === 'BE') {

    /**
     * Registers a Backend Module
     */
    \TYPO3\CMS\Extbase\Utility\ExtensionUtility::registerModule(
        'MINAV.' . $_EXTKEY,
        'web',     // Make module a submodule of 'web'
        'm1',    // Submodule key
        '',                        // Position
        array(
            'Slider' => 'list, show, new, create, edit, update, delete, copy',
            'Slide' => 'list, show, new, create, edit, update, delete, upload, paste',
            'Item' => 'list, show, new, create, edit, update, delete, upload, paste',
        ),
        array(
            'access' => 'user,group',
            'icon'   => 'EXT:' . $_EXTKEY . '/ext_icon.gif',
            'labels' => 'LLL:EXT:' . $_EXTKEY . '/Resources/Private/Language/locallang_m1.xlf',
        )
    );

}

The expected template file is stored in this path:

typo3conf/ext/layerslider/Resources/Private/Backend/Templates/Slider/List.html

and if i copy this file to this location:

typo3conf/ext/layerslider/Resources/Private/Templates/Slider/List.html

Why is in 7 the module.tx_layerslider.view ignored?
