[TYPO3-calendar] Missing textarea in Fe-Editing after Update 1.3.3 -> 1.4.3

[Tobias Schaefer]

Hi,

after updating TYPO3 from 4.5 to 4.7 and cal from 1.3.3 to 1.4.3 the textarea of Fe-Editing is missing (see screenshot).
In the HTML-sourcecode the textarea has a width and height of 0px and no rows and cols:
<textarea id="RTEareatx_cal_controller_description__1" name="tx_cal_controller[description]" rows="0" cols="0" style="width: 0px; height: 0px;"></textarea>
I changed from classic to standard-template and css and deleted and re-inserted the Fe-Editing-template.
I hope someone can give me clue.

Cheers, Tobias
