[TYPO3-dam] Possible bug/problem with DAM and TYPO3 4.3.0alpha1

[Erik Svendsen]

I'm testing TYPO3 4.3.0alpha1 at some develop installation, and have stumbled 
upon some weird behavior with htmlArea and DAM 1.1.1. I suppose the problem 
is in DAM, because the installation without DAM hasn't the problem.

If I insert a picture in the editor and load the page with the content element 
in the frontend, I get the following error.

Catchable fatal error: Argument 2 passed to tslib_cObj::isClassAvailable() 
must be an array, null given, called in /var/www/html/typo3_src-4.3.0alpha1/typo3/sysext/cms/tslib/class.tslib_content.php 
on line 5989 and defined in /var/www/html/typo3_src-4.3.0alpha1/typo3/sysext/cms/tslib/class.tslib_content.php 
on line 6417

I have tried with different configuration i Page TSConfig (as written in 
the manual), turned of Media tag and/or htmlArea integration, with no difference.

As far as I understand is "isClassAvailable" a new functionality in TYPO3 
4.3, so the problem could also be in the Core code.

Before a possible "notice" in the bugtracker (if this are a bug it should 
be solved before version 4.3 hits the world), I would check if others have 
the same problem.
