Alright Guys I fixed this casting problem, I need to put everythig in
XML instead of Arrray, it is dropping fields from one list to other now,
but now i came up with another problem which is that I need to move
fields from list 1 to list 2, However it is allowing me to move from
list one to 2nd but not from 2nd to first. The way i enable move is with
the dragMoveEnabled property true. Below is the code for the both the
list. Please let me know how would i enable move back from the second
list to the first one.
Thanks again for your help.

Hi Guys
I am trying to drag contents of one list and drop it into the second
List.
I am having issues that first list has values from XML List Collection
and only i need is the 'id' attribute of the XML and I am successful
in getting XML List in 1st list. I am using HTTP Service. Now my
problem is that when i am trying to drag and drop the fields from
first list it puts filed in the second list with [object,object]. I am
using array to grab values from 1st list. I have attached the code.
Anyone has any idea where I am messing things. To me it looks like
casting problems. Please let me know how would I fix this issue as I
only need the same field from one list to other.
Thanks a lot for you help guys

Re: [flexcoders] Casting Problem Dragging from one list and Dropping into another
That's interesting because I am using the same code for both the lists, for
both the lists I am enabling dragmove enabled property true. In short they
all have the same property defined, so technically they should work but
that's my surprise that they work one way and i cannot drop back.
I have no idea Tracy.
Please let me know if you have any.
Also if it helps should should i change my approach of drag and drop because
as far as i know you can do drag and drop multiple ways, either directly
defining source and destination or using all function drag enter , drag exit
and drag complete.
Pls let me know if you have any altenative.
Thanks
