Sorry,

I forget my config files infos and other stuffs: (I've included a complete list of used jar files inside jsf-libs and WEB-INF/lib/ directories)

my ui:addremove declaration on xhtml

I've just got out on this.

The solution was replace all netbeans stuffs (ui:image, ui:addremove, ...) by trinidad components :(

I got the examples from trinidad on jboss-seam-cvs/trinidad.

TIP: to replace cascating style sheet from trinidad core skins, just put our style class somewhere before trinidad/adf .css declaration...
