Hi Thomas,

OK, thanks. Now it's more clear to me what you're trying to do.

Something like this should work:

<cc:interface>
    <cc:attribute name=3D"button1" type=3D"insert.package.here.SimpleModel"=
 />
</cc:interface>
<cc:implementation>
    <h:commandButton disabled=3D"#{cc.attrs.button1 =3D=3D null}"
action=3D"#{cc.attrs.button1.myaction}" value=3D"Button1" />
</cc:implementation>

Regards,
Jakob
