TYPO3 Core

the XCLASS for backend.php is ignored - apparently it has used so that XCLASS declarations come always too late.

So class ux_TYPO3backend extends TYPO3backend

the ux_... has not used at all.

This happens also for some other core files and that makes XCLASSing impossible.

So it would be nice if the function 'setStartupModule()' would have hook in order to reset the variable '$startModule'

// here needed a hook to reset '$startModule'

if($startModule) {
$this->js .= '
// start in module:
function startInModule(modName, cMR_flag, addGetVars) {
Event.observe(document, \'dom:loaded\', function() {
top.goToModule(modName, cMR_flag, addGetVars);
});
}
