How would I do that if I want to use data binding?
I tried something like list.bind("selection", btnUp, "enabled", {
converter : function(value,model){
return (value.getSort_order() > 1);
}}
but the converter doesn't get fired on change of selection. Should I bind to
something else? I've also tried binding to the list.getSelection() object,
but it seems there is no property to bind to...
