[TYPO3-mvc] multiple conditions in if viewhelper

[Simon Schaufelberger]

hi,
i want to make a condition with multiple things i want to check for like 
this:

<f:if condition="{first} == 0 || {second} == 0 || {third} == 0">

but now i get an exception:
#1244201848: The expression "0 == 0 || 0 == 0 || 0 == 0" has more than 
tree parts.

why do i get an exception like that? is there any workaround?
