resolved, I just overrided the render method:
Column<MyDataProxy, String> deleteColumn = new
Column<MyDataProxy, String>(
new ButtonCell()) {
public String getValue(MyDataProxy c) {
return "Delete";
}
@Override
public void render(Context context,
MyDataProxy c, SafeHtmlBuilder sb) {
if (c.isManualAdded())
super.render(context, c, sb);
}
};
and the button is rendered only for manual added informations!
