Bug #63364
Updated by Helmut Hummel almost 10 years ago
In the @\TYPO3\CMS\Core\Resource\ResourceStorage@ it is possible to set a the class property @$evaluatePermissions@.
If this is @FALSE@ no check for filemount boundaries should be performed.
The new feature for read only filemounts has introduced a regression here because the check for this new flag does not respect this setting.
Another problem is that this check in the @checkFileActionPermission()@ method can also fail when the user has multiple filemounts, one which allows writing and one which is read only because it breaks on the first read only filemount.
