[flexcoders] How to get a item in Arraycollection?

[markflex2007]

Hi,

I have a demo here:

acTest = new ArrayCollection([{first: 'Matt', last:
'Matthews'},{first: 'Jame', last: 'Wang'},{first: 'Rey', last:
'Chang'}]);     
                        
trace(acTest.length.toString());
trace(acTest.list.source[0].first);

I want to use 'acTest.list.source[0].first' to get "Matt".but I can not.
Please let me know the correct syntax.

I am new for Arraycollection and I like to learn.Please help me.

Thanks a lot

Mark
