I need to convert an array to seperate vars and keep the old message.  
this is how i solved it but i think there is a better way to include the old message in the new one other then include all vars one by one....like i did...

var msg\_copy = RED.util.cloneMessage(msg); // menu,  
msg = JSON.parse(JSON.stringify(msg.fq[msg.fq\_a]));

// define the old msg again from the copy  
msg.fq = msg\_copy.fq;  
msg.fq\_l = msg\_copy.fq\_l;  
msg.fq\_a = msg\_copy.fq\_a;

return msg;
