TYPO3 Core

I have the same Issue. 'internal_type' => 'file', works, 'folder' breaks.

'folder' => array(
            'exclude' => 1,
            'label' => 'LLL:EXT:nbogallery/Resources/Private/Language/locallang_db.xml:tx_nbogallery_domain_model_gallery.folder',
            'config' => array(
                'type' => 'group',
                'internal_type' => 'folder',
                'show_thumbs' => '1',
                'size' => '3',
                'maxitems' => '200',
                'minitems' => '0',
                'autoSizeMax' => 40,
                'disable_controls' => 'upload',
            ),
        ),

Problem still exists in TYPO3 6.1 (found it in ke_search file indexer).

PHP Catchable Fatal Error: Argument 1 passed to TYPO3\CMS\Recordlist\Browser\ElementBrowser::TBE_expandSubFolders() must be an instance of TYPO3\CMS\Core\Resource\Folder, null given, called in /html/typo3/typo3_src-6.1.0/typo3/sysext/recordlist/Classes/Browser/ElementBrowser.php on line 1278 and defined in /html/typo3/typo3_src-6.1.0/typo3/sysext/recordlist/Classes/Browser/ElementBrowser.php line 1453

Problem comes when no folder is given. (usually when a plugin or a record is initialized)

One solution would be to set the "selectedFolder" in user's default upload folder by default when no folder is given as it's done with "file".

Adding this at line 1269 in typo3/sysext/recordlist/Classes/Browser/ElementBrowser.php solve the problem:

// Or get the user's default upload folder
if (!$this->selectedFolder) {
    $this->selectedFolder = $GLOBALS['BE_USER']->getDefaultUploadFolder();
}

Still got the error in 6.1.4 and ke-search. Your Patch solves the problem. Thanks Matthias and Benjamin!

Patch applies successfully on Typo3 6.1.5 and solves the issue. Thank you Matthias and Benjamin!

I got the same problem with TYPO3 6.1.5.
Can someone send a patch to gerrit and then the review process can begin?

The same in TYPO3 6.2...

I don't know, personnaly I use it in a custom extension...

Thanks

ke_search uses this feature.

Error is still there with current master of TYPO3 CMS.

Test case:

• Install TYPO3 CMS blank package
• Install ke_search
• [with ke_search 1.5] set compatibilty version to 6.2.99 in ext_emconf.php
• Create a sysfolder
• Create a record of type "indexer configuration", set the type to "file"
• In the field "Directories" try to select a directory

Error message:

PHP Catchable Fatal Error: Argument 1 passed to TYPO3\CMS\Recordlist\Browser\ElementBrowser::TBE_expandSubFolders() must be an instance of TYPO3\CMS\Core\Resource\Folder, null given,

Confirmed ke_search uses this feature. Is there a patch for 6.2.0beta2 ?

I create a small extension to test the behavior. So it is
easier to test for all of you.

You can find the extension on github.
https://github.com/markusguenther/internaltype

Only clone it in your typo3conf/ext folder.

cd typo3conf/ext
git clone https://github.com/markusguenther/internaltype.git

After clearing the cache you can create a new record from type test object and can use the element browser for the property album.

Thats all. Thanks for testing!

This patch did not solved it in 6.2.0.

I applied the last patch, then the folder tree appears. But now a can't select any folder without an exception:

#1392409507: Invalid form/module token detected. Access Denied! (More information)

UnexpectedValueException thrown in file
/<path>/typo3/mod.php in line 39.

Bump!

Update from 6.2.0 to 6.2.4 because of this issue - still same

Would be great if you could fix this in the short run

Need to finish an ext in the next few weeks in which the user has to be able to pic a folder as a starting point

Some additional infos:

If using folder in FlexForms i get following error from error log:

PHP Fatal error: Call to a member function checkActionPermission() on a non-object in 
.../typo3/sysext/recordlist/Classes/Browser/ElementBrowser.php 
on line 1732, 
referer: http://www.vagrant-typo3.dev/typo3/browser.php?mode=folder&bparams=data[tt_content][177][pi_flexform][data][sDEF][lDEF][settings.explorer.root][vDEF]||||"

By changing

<internal_type>folder</internal_type>

<internal_type>file</internal_type>

and choosing some file and save changes(***).

and then changing back to

<internal_type>folder</internal_type>

it is possible to create new entries and choose folders or change created above entries(^ ***).

But by relogin in Backend i get Fatal errors from above again.

I can confirm that, using the current state of the patch, I am also getting the error message upon attempting to navigate through the tree on the left.

#1392409507: Invalid form/module token detected: Access Denied! (More information)

UnexpectedValueException thrown in file
.../www/typo3_src/typo3/mod.php in line 26.

However, selecting the folder displayed by default on the right works.

Tested in TYPO3 6.2.7.

Is this issue fixed with latest git revision of TYPO3 7?

This issue is fixed in 6.2.10rc1!

Big kudos and thanks to all involved developers :)
