[TYPO3-asia] Extension not working after upgrade from 4.2 to 4.5

[Radovan Hlavaty]

Hello,

I've just made an upgrade of TYPO3 from version 4.2.3 to 4.5.40. The upgrading process went well and most of the extensions are working, however there is one custom extension which doesn't work. If I try to load a page where the extension should be loaded it gives me this error: Fatal error: Class 'tx_ejotazka_pi1' not found in C:\wamp\www\comseco_svn\htdocs\t3lib\class.t3lib_div.php on line 5468.

I have checked the line 5468 and found out that there is method instantiateClass, which is called inside method makeInstance.
Here I've mentioned 2 changes from the previous TYPO3 version. First, the method makeInstance was previously &makeInstance.
Second, there wasn't the method instantiateClass.

I don't understand why all the other extensions are working but this one. The only difference is that the instance of this extension is made in some other extension/plugin. This is the code that calls makeInstance method at first.

$otazka = &t3lib_div::makeInstance('tx_ejotazka_pi1');
$otazka->main($content,$conf);

I would appreciate any advise. Thanks in advance.
