Hi guys

I seem to be having problems sending serialized data to my ajax script. The following script produces Error: 411 -- Length Required

Any ideas what this could be?

PHP Code:
    Sortable.create("column5", {
        
dropOnEmpty:true,
        
tag:'div',
        
containment:["column3","column4","column5"],
        
constraint:false,
        
hoverclass:'columns-hover',
        
handle'handle',
        
ghostingtrue,
        
onUpdate: function() {
            new 
Ajax.Request('ajax_controllers/update_content.php', {
                    
method:'post',
                    
parameters: {
                        
data:Sortable.serialize('column5')
                    },
                    
onSuccess:handlerFunc,
                    
onFailure:errFunc
                
}
            );
        }        
    }); 
Any help would be much appreciated

Thanks in advance
