Hi,
I've tried what you suggested. I've done the inheritance from SlideBar and
included/added the needed parts, and now I get those errors :
There is no event handler for the event 'addItem' on target
'editor.components.core.SlideBarList[4k0]'!
There is no event handler for the event 'removeItem' on target
'editor.components.core.SlideBarList[4k0]'!
So i assume that we're getting close of something :-)
By the way, to handle those events, should I write my own handlers or should
I have to include more stuff ?
Viele danke Christian !
David
