RE: [flexcoders] mx_internal_uid Problem in Add Data

[Alex Harui]

You could also have done
 
private function addFromTopDG():void {
    var obj:Object = ObjectUtil.copy(fromDG.selectedItem);
    delete obj.mx_internal_uid;
    (toDG.dataProvider as ArrayCollection).addItem(obj);
    obj = null; 
   }
 
We would auto-generate it for you.

Alex:
Thanks,
I edited the code :
private function addFromTopDG():void {
    var obj:Object = ObjectUtil.copy(fromDG.selectedItem);
    obj.mx_internal_uid = UIDUtil.createUID();
    (toDG.dataProvider as ArrayCollection).addItem(obj);
    obj = null; 
   }
 
this way can change the uid,
& you said I can delete the uid before copy it ,can you give me an
example?thanks

        If they are truly the same data, you should prevent them from
being added twice.
         
        If they are clones/copies, then you can always delete the uid
before copying it.  However if you use strongly-typed classes instead of
dynamic objects you shouldn't have this problem provided you clone them
using ObjectUtil

        the problem is that when I add the selectedItem data from fromDG
to
        toDG twice or more.
        U can find the mx_internal_uids are the same value, It causes
problem
        that the DG thought that 
        they are the same object. Of course, I can't mousefocus in it. 
        
        Any One can help me?
        Thanks!
