[TYPO3-dev] Extensionbuilder saveWiring is not working

[simon.ittmann at web.de]

Hi,

i got a little problem. Since two days it's not possible to save modeling changes with the extension builder.
I'm using typo3 version 7.2.0.
Listing the wirings and adding new items is working reliable. After pressing the save button (method= saveWiring) an error message is thrown(No Sub Action!).

The problem is the parseRequest function in ConfigurationManager.php. The incoming Json String content looks correct, but it's not a valid json.
Here is the json part with the error:

{\"allowedFileTypes\":\"\"":false,\"relationDescription\"

If someone got any idea how this could happen, or how to fix this problem please contact me. 

Best regards, 
Simon Ittmann
