[TYPO3-v4] [TYPO3-dev] feeditadvanced and 4.5 introduction-package

[Steffen Ritter]

Hello list,
i just installed the introduction package of TYPO3 4.5.0 and added one 
extension: feeditadvanced.
The Icons in fe are shown, but I only get an endles loading form, 
dragging new elements does not work. looking at the query the answer 
throws no error and seems to be ok...

any ideas? is this a known incompatibility?

regards

Steffen

P.S.: This is crossposted as follow-up, disccussion should go to v4
