[TYPO3-mvc] Fluid Checkbox

[Yolf]

Hi,

I have also a problem with checkboxes (case where the TCA includes an 
"items" array). I am able to correctly generate the form elements but 
when I try to update the data in the controller, I get the following 
error when two or more checkboxes are selected:

#1247602160: Operand should contain 1 column(s)

I have declared the variable associated with my checkboxes as "@var 
array" in the model. As far as I understand the problem, the data used 
for update contain an array associated with my selected checkboxes. I do 
not see how to have this array correctly converted into the integer that 
should represent the selected checkboxes.

Thanks in advance for any help.
