[flexcoders] Not showing proper data in a task chart from an XML

[max_fas83]

I'm using ILOG Elixir to display a task chart, i took the basic code from Tour 
de Flex and changed the code slightly for me, an XML is generated using my java 
application.

When i use almost exactly the code from Tour de Flex (static file retrieval) 
the code is show just fine, without any problems.
however when i change it to httpService to generate the charts dynamically the 
information is not shown correctly: All tasks no matter if it's a summary or a 
leaf are shown as a leaf (a green thick bar instead of a blue thin bar). Also 
if a summary have only one leaf inside, the summary is shown as if it doesn't 
have any leafs.

i would appreciate any help i could get.

my code looks like this:

<?xml version="1.0" encoding="utf-8"?>

and the xml looks like that:
