[TYPO3-project-formidable] renderlet:CHECKSINGLE only works one way

[Till Janetzki]

Hi,

in Formidable 2.0.289 the renderlet:CHECKSINGLE seems to be working only 
  one way. If I check the Box and submit, everything is fine and saved. 
But if I uncheck the Box and submit the value is not stored in the 
database. The Textbox works just normal...

I tried with the following example XML, maybe I'm missing something ?

Best regards
Till Janetzki
