Error with eval 'path' in file picker

4.13.30

Description

When I restrict the path in a DCA,

$GLOBALS['TL_DCA'][$strTblName]['fields']['mcwtest1'] =
    [
        'exclude'   => true,
        'inputType' => 'multiColumnWizard',
        'eval'      => [
            'minCount'     => 3,
            'maxCount'     => 5,
            'columnFields' => [
                'col_image'   => [
                    'label'     => 'Grundriss',
                    'exclude'   => true,
                    'inputType' => 'fileTree',
                    'eval'      => [
                        'fieldType'  => 'radio',
                        'files'      => true,
                        'filesOnly'  => true,
                        'extensions' => \Contao\Config::get('validImageTypes'),
                        'mandatory'  => true,
                        'path'       => 'files/content/images',
                    ],
                ],
...

At first, we see image 1:

the following errors result:

• if one clicks on a (sub)folder, no more files are displayed (image 1).
• if you click on a level in the breadcrumb that is higher than the given path, nothing is shown anymore (picture 2)

Current workaround: if you know some of the image names, the search still works...

first image = image 0 😂

What was your selected bredcrumb/current-dir in the filemanager beforehand?
I suspect it is related to an issue i experienced here

[zonky2]

see the path value: files/content/images

Image 0 : I thought somewhere the filenames are output... the first one starts with 0 ;-)

see the path value: files/content/images

I dont mean your dca setting but the thing that is stored in session (or localstorage) when you go to the filemanager and click on the folder-icon of files/othercontent so it is displayed in the breadcrumb.
Is your fileTree-Input then able to show something from files/content/images?

Does this issue also appear if you do not use the multiColumnWizard widget?

[zonky2]

the same behavior occurs with MetaModels - there you can specify a starting point at file attribute

I used the MCW to exclude MM or DCG and because it was easy to build a test case... with RST-CE this is surely also possible

same bug at Contao (testet on C 4.13.34)

change at tl_content.php

contao/core-bundle/src/Resources/contao/dca/tl_content.php

Lines 246 to 256 in 8114301

	'singleSRC' => array
	(
	'exclude' => true,
	'inputType' => 'fileTree',
	'eval' => array('filesOnly'=>true, 'fieldType'=>'radio', 'mandatory'=>true, 'tl_class'=>'clr'),
	'load_callback' => array
	(
	array('tl_content', 'setSingleSrcFlags')
	),
	'sql' => "binary(16) NULL"
	),

and set your own path

        'singleSRC' => array
        (
            'exclude'       => true,
            'inputType'     => 'fileTree',
            'eval'          => array(
                'filesOnly'  => true,
                'fieldType'  => 'radio',
                'extensions' => \Contao\Config::get('validImageTypes'),
                'mandatory'  => true,
                'tl_class'   => 'clr',
                'path'       => 'files/content/images'
            ),
            'load_callback' => array
            (
                array('tl_content', 'setSingleSrcFlags')
            ),
            'sql'           => "binary(16) NULL"
        ),

hat den jemand den Bug auf dem Schirm? insgesammt etwas misslich für die Usability ohne mögliche Vorauswahl :(

[leofeyer]

The issue only occurs if the file manager breadcrumb menu is active:

@contao/developers How do we solve this?
