TYPO3 Core

Hi there,
had the same errors.
try to update PMK Textarea Widget - pmktextarea to current version (http://typo3.org/extensions/repository/view/pmktextarea/0.3.0/)

This solved my problems.

Hm, could not reproduce this on a clean 4.2 installation.
But if an XCLASS overwrites some core methods (like e.g. the mentioned extension does), it might lead to a similar behaviour you mentioned.

Thus, you should addtionally check the XCLASS environment on your system...

I repeated the following steps and reproduced the errors:

1. "normal" installation of typo3 4.1.2
2. before updateing to 4.2.0: creating symlinks
3. installing 4.2.0
4. changing symlinks
5. login to new backend
6. errors occured
7. updating pmktextarea from version 0.2.0 to 0.3.0
8. errors gone

Hope it helps in my case.

Note: Of course i deleted all cached files (typo3 and browser) after step 4.

Hi,
i had the same errors.

I updated from version 4.1.5.
In 4.1.5 there was a Firefox bug and i needet the extension mn_ff3_be_bugfix.
This extension used XCLASS, and these extensions can produce some problems.

After deinstall mn_ff3_be_bugfix this problem was fixed.

Look also in your Configuration->$TYPO3_CONF_VARS->BE->XCLASS for other extensions, that used XCLASS.

Not a problem of the TYPO3 Core... extension related...
