[Typo3] clickmenu(CSM) for database elements

[Gerd Reise]

Hi everybody,

I am trying to add a clickmenu on database elements in a module. I already
wrapped images with template::wrapClickMenuOnIcon(). I inserted the standard
html and js via template::getContextMenuCode():

Everytime I click  on the icon no menu is displayed and the top frame says:
page not found.

Do I have to define a clickmenu first ?
Anyone got experience with this problem ?

Greetings,
Gerd
