Modification the Configuration Programatically at rumtime

Question

I developed a form Called start_project.fmb containing a push-button through which I call a form called movies.fmb, each one has the associate java classes.
1)
At run time
start_project.fmb has url
http://meteo-49aba7b5b:8888/forms90/f90servlet?*config=meteo*
movies.fmb has url:
http://meteo-49aba7b5b:8888/forms90/f90servlet?*config=webutil*
2)
when I run start_project.fmb , URL in the browser is:
http://meteo-49aba7b5b:8888/forms90/f90servlet?*config=meteo*&form=C:\Dev9i\forms90\Meteo_Projet\Start_Project.fmx&userid=METEO/METEO@dbrc&buffer_records=NO&debug_messages=NO&array=YES&query_only=NO&quiet=NO&RENDER=YES
when I called movies.fmb, URL in the browser is:
http://meteo-49aba7b5b:8888/forms90/f90servlet?*config=meteo*&form=C:\Dev9i\forms90\Meteo_Projet\Start_Project.fmx&userid=METEO/METEO@dbrc&buffer_records=NO&debug_messages=NO&array=YES&query_only=NO&quiet=NO&RENDER=YES
Each one is running well alone, but when I call movies.fmb from project.fmb by pressing the associated button, this one is not running well because it did not take its configuration ( config=webutil ) already defined in formsweb file,
how can force the movies.fmb to take config=webutil programmatically, when I called him from start_project.fmb
Any help I appreciate it
Thank tou.

Well, I finally found a workaround using some "side-thinking".
Actually, the reportcrystalviewer class is able to "understand" what to do with dynmic parameters, and according to each parameter configuration it creates specific javascript code to populate each field. Looking at page source code when a crystalreportviewer is showing parameter prompt, it is easy to find what it looks like a select control name and id.
To check if it is accesible, I added an html button to same page and set an onclick alert showing that control "innerHTML", and the magic is done! It showed all options tags ready to be used as it where a normal html select control.
So we will code some logic to read this "ready-to-use-html" from the dynamic controls we need to use. The problem is that we do not want to show the crystalreportviewer in the same page and still be able to read the parameter prompt out of this control.
It seems it can be achieved by calling the "Render" method of the crystalreportviewer to a texthtmlwriter connected to a memory stream, and once rendered make it invisible or clear it from page control collection. And that's all! Then it's time to go over the memory stream, find the dynamic parameter associated control in html and copy the html into the new customized prompt.
We will use this workaround for the moment.
Thanks!
