Embed Open Flash Chart on Laszlo web application

Open Flash Chart is a charting component which allow to be embedded into 3rd-party web applications.
it's free, open source and powerful. Works very well with PHP, .NET, JAVA and so on, except that you can not embed into your flash application.
I recently found this problem while trying integrating with a web application written on OpenLaszlo framework. unfortunately, there was no patch nor workaround solution. I've been trying refactoring the code myself, finally made some progress.
Here is the results:

Now I can load 2 chart instances in a flash movie.
I attached the chart including test file and modified source code OFC version 1.9 for someone who interests.

Summary the steps I've done:

1. add context:MovieClip to all constructor function of almost classes as first parameter, except MinMax, Css, Size, Square, Style, XLabelStyle, YLabelStyle, YTicks. similarly added the member variable public var _root:MovieClip; into these classes.
2. in the constructor function of all above classes, i assigned _root = context; to overwrite all _root variable using in the scope.
   
3. if the constructor function has called super(...) I changed all to super(context,...).
4. Search all phrase new class(...) where class is all the class names have been changed above, replace by new class(_root,...)
   
5. at the beginning of open-flash-chart.as I assigned:
   _root.width = _parent._oldroot.width; _root.height = _parent._oldroot.height; _root.data = _parent._oldroot.data;
   In order to overwrite these variables passed by web browser.
   Note that the variable _parent.oldroot will be set inside the external flash application later.
6. in the flash application which load OFC, I add following code:
   _root.data = "http://127.0.0.1:8080/lps-4.0.3/openlm/data1.txt"; _parent._oldroot = _root; this._lockroot = true; this.loadMovie('../open-flash-chart.swf');
   note the highlight lines, it's very important to make the chart works correct.

it seems to be only that (if i don't forget anything else).
