[TYPO3] icon on a menuitem

[PEF]

Hi all,

Need to add an icon to one particular menu-item in a GMENU.

menuitem 1
menuitem 2 + icon
menuitem 3
...
a.s.o

I've tried to solve this by adding a section:
30 = IMAGE
30 {
    file = ...
    if {
      value = 83,99,121
      isInList.data = page:uid
    }
}

But this doesn't seem to work. I got icons on every menuitem.

Do I really have to make a "fakemenu " to solve this, or do I just 
missed a simple point?
