[TYPO3-dev] Bug or wrong TS?

[Christian Lerrahn]

Hi,
I have set up a GMENU in TYPO3 3.8.1 like this

temp.homeMenu.1 {
   applyTotalW = 10
   NO {
     XY = 130,32
     10 = IMAGE
     10.file = fileadmin/templates/bg.png
     20 = TEXT
     20 {
        offset = 10,15
        align = left
        text.field = title
        text.case = upper
        fontFile = fileadmin/fonts/verdanab.ttf
        fontSize = 10
        fontColor = #ffffff
     }
   }
   RO < temp.homeMenu.1.NO
   RO = 1
   RO {
      15 = IMAGE
      15.file = fileadmin/templates/tab.png
   }
}

The tab contains a transparent area.
The problem is now that if I move the mouse over one of the tabs, the 
roll over will be shown but in the transparent area, you will not see 
the picture from 10 but the background of the site. As the tab is added 
with a higher number, isn't it supposed to be merged on 10? In any other 
case, I would just set up a GIFBUILDER object but here I can't really do 
that because 10 is applied to all the menu whereas 15 (the tab) is only 
an element for one menu entry. I have to do this for complex 
transparencies in the menu.
Is TYPO3 supposed to merge 10 on 15 or not? I feel that this would 
logically follow from the fact that 20 is merged on 10 (and 20 is still 
merged on 15), wouldn't it? As I haven't ruled ot the possibility of a 
lack of understanding on my side, I weanted to post that here before 
filing a bug.

Cheers,
Christian
