[flexcoders] Filter an ArrayCollection into an ItemRender

[luis_roman_am]

Hi people!  Situation as follows:

MYARRAYCOLLECTION (Example fields)
    - TITLE 
    - URL

INDEX.MXML
    - TILELIST
          - DataProvider="{MyArrayCollection}"
          - ItemRenderer ="MyRenderer"


MYRENDERER.MXML
    - LABEL (data.TITLE) (WORKS FINE)
    - LINECHART
        -DataProvider="Application.application.MyArrayCollection}
(PROBLEM HERE)

THe problem is: How can i filter linechart inside MYRENDERER.MXML the
  dataprovider to receive only data for the items with his URL?

I tried something like:
    
-DataProvider="Application.application.MyArrayCollection.(@Url=data.Url)}

but this throws me the following error:

Error #1123: Filter operator not supported on type mx.arraycollections.

Please Help!!
