Ok I found thanks to http://jboss.com/index.html?module=bb&op=viewtopic&t=146087
My ask is "closed" thanks to everyone for yur help!!
I thought it was closed but it was a mistake, it was just a coincidence that I didn't had the duplicate Id error.
Now that I have more datas so more menus, I always get the duplicate Id error...
I really need a dynamic menu so is there any solution please?
I thought about using the TREE object but when I test the example from the demo it seemes the keys have to be integer and I need String.
For exemple if I put this in the simple-tree-data.properties it works:
1=Daniel Defo
1.1=Robinson Crusoe
1.1.1=Start In Life
1.1.2=Slavery And Escape
But if I put this then it don't work:
ABC=Daniel Defo
ABC.DEF=Robinson Crusoe
ABC.DEF.GHI=Start In Life
ABC.DEF.JKL=Slavery And Escape
So please, is there any solution that will allow me to build a dynami menu because I really need it ?
Thanks
