[TYPO3-dev] Move up/down in frontend

[Tapio Markula]

Hi

What is the idea of this change

Typo 4.0.1
$res = $GLOBALS['TYPO3_DB']->exec_SELECTquery(
											'uid,pid',
											$table,
											'pid='.intval($row['pid']).
												' AND '.$sortField.$op.intval($row[$sortField]).
												$copyAfterFieldsQuery.
												$GLOBALS['TSFE']->sys_page->enableFields($table,'',$ignore),
											'',
											$sortField.$desc,
											'2'

Older:

$res = $GLOBALS['TYPO3_DB']->exec_SELECTquery(
												'uid,pid',
												$table,
												'pid='.intval($row['pid']).
													' AND '.$sortField.$op.intval($row[$sortField]).
													$copyAfterFieldsQuery.
													t3lib_pageSelect::enableFields($table,'',$ignore),
												'',
												$sortField.$desc,
												'2'
											);

difference in one row

The change cause error message

Fatal error: Call to a member function enableFields() on a non-object in 
/var/www/customers/tyouupumuskeskus/public_html/t3lib/class.t3lib_tsfebeuserauth.php 
on line 1068
used with my evaluation verion of tm_contentaccess.

Making an XCLASS which force to use the older version,
the error message disappeared and move up/down worked again.
Can I safely force to use the older version?

If I want to make it compatible with mk_tvfrontend I must add
redefine
function extEditAction()	

But I can't understand changes, which just cause error messages.
