[TYPO3-core] RFC #16463: Bug: Custom configured modules can't be enabled for non-admins

[Bastian Waidelich]

Hi all,

This is an SVN patch request.

Type: Bugfix

Bugtracker references:
http://bugs.typo3.org/view.php?id=16463

Branches:
trunk, 4.4(?)

Problem:
When registering a BE module in your extension by specifying a custom 
configureModuleFunction handler (in 
$GLOBALS['TBE_MODULES']['_configuration'][$name]['configureModuleFunction']), 
the module won't show up in the BE user / BE group TCE form, making it 
impossible to enable it for non-admins.

Solution:
The problem is, that the method checkModAccess() is not called in 
t3lib_loadModules. This method has the side effect of adding the module 
to the modListUser/modListGroup array. See attached patch.

Notes:
Without the patch, the module won't show up in the BE user / BE group 
TCE form but it will be visible to all users!
So actually the module will be *always active* unless the module checks 
the access again.
Sidenode: This affects all Extbase modules. There the access is checked 
again in the bootstrap, leading to an exception when the user tries to 
load the module.

All the best and happy birthday, beta1
Bastian
