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

Regards,
Jakob
