[TYPO3-mvc] form.select add empty option

[Stefano Cecere]

hi Claus

i tried to understand, from  
http://fedext.net/fed-viewhelpers/form/select-option.html
how to add an "empty" field before my objects arrays.. but could not :(

so i ended up with the ->toArray() solution (and then merging the 0 =>'--'  
in the controller before giving the array to Fluid

ciao
