Flex arraycollection sorting not working

Question

I am trying to sort a list of string stored in an arraycollection. But the sorted result is not correct. Please see my code.

spark.collections.Sort

if(value is ArrayCollection){
            var sort:Sort=new Sort();
            var sortField:SortField = new SortField("data")
            sortField.numeric=false;
            sort.fields=[sortField];

            ArrayCollection(value).sort=sort;
            ArrayCollection(value).refresh();
        }

Input: Start With, Contains, End With, Equals IgnoreCase, Not Equals, Matching, Equals

Output: Equals IgnoreCase, Contains, End With, Start With, Not Equals, Matching, Equals

Some time only one row is swapping with another(as above), some time no sorting at all.

Everything is ok here. You need to provide some more details about your collection. Does the elements in value have values in the data field? — nakib, Dec 13 '12 at 10:11
Just guessing: it's sorted like [alpha, beta, Alpha, Beta] and you want [alpha, Alpha, beta, Beta]? — RIAstar, Dec 13 '12 at 10:21

In case of your array collection having list of string. you need not specify name of SortField your case data.

            var value:ArrayCollection = new ArrayCollection(['Start With','Contains','End With','Equals IgnoreCase','Not Equals','Equals']);
            var dataSortField:SortField = new SortField(); //Leave it empty.
            dataSortField.numeric = false;

            var dataSort:Sort = new Sort();
            dataSort.fields=[dataSortField];

            value.sort = dataSort;
            value.refresh();

o/p:

   "value"  mx.collections.ArrayCollection (@31ced61)   
[0] "Contains"  
[1] "End With"  
[2] "Equals"    
[3] "Equals IgnoreCase" 
[4] "Not Equals"    
[5] "Start With"

If arraycollection having object with data property your code is absolutly correct. like

            var value:ArrayCollection = new ArrayCollection();
            value.addItem({data:'Start With'});
            value.addItem({data:'Contains'});
            value.addItem({data:'End With'});
            value.addItem({data:'Equals IgnoreCase'});
            value.addItem({data:'Not Equals'});
            value.addItem({data:'Equals'});

This case you need to specify like

var sortField:SortField = new SortField("data");

I removed the 'data' attribute and it worked. Thank You @Raja :) — Saju, Dec 13 '12 at 13:36
