REP-51018 + REP-50004 Errors (Urgent)

Question

Hello,
I am working under Oracle 9i iDS on Windows XP Pro.
When I invoke my WebReports from WebForms, I see my Parameter Form that Pops-Up in a new Browser window.
When I hit, the "Submit Query" button, I am prompted to enter the username/password/database information.
I also get a message like:
REP-51018: Need Database User Authentication
I enter the required parameters even though they are already defined by the application code. Then I get an error like:
REP-50004: No Report specified on the command line.
1) Why do I get these errors ?
When I relauch my WebReport from WebForms, it works fine and I can get a WebReports from the WebForms.
2) What is going on ?

PS: I created a generic function called RUN_REPORT_OBJECT_PROC that uses the run_report_object() and web.Show_document built-ins as indicated in:
http://www.oracle.com/technology/products/forms/pdf/10g/frmrepparamform.pdf
PS2: I increased the SESSIONS parameter in the init.ora file and set its value to 9999, but still cannot resolve the issue.
PS3: I get the same REP-51018 error under Forms/Report Services 10g on my Linux box.

Hello,
I used the generic RUN_REPORT_OBJECT_PROC presented in the white paper. The generic procedure makes calls to the run_report_object and the web.show_document built-ins.
The only modification that I have done to this generic function is to add the SYNCHRONIZE keyword before the call to web.show_document built in as was suggested by a technical note on Metalink.
The RUN_REPORT_OBJECT_PROC also makes a call to the ENCODE function which I have also added.
In addition in my WebReports, I added the 3 user parameters: P_ACTIONS, P_SERVER_NAME and P_USER_CONNECT as well as added code to the BeforePForm trigger as indicated in the white paper.
All very straight forward stuff.
On Oracle 9i iDS running under Windows XP Pro, I can generate the Parameter Form then get the REP-51018 followed by the REP-50004 errors when pressing the "Submit" button. If I come back and press the "Reset" button on my Parameter form, I can generate the corresponding WebReport without errors.
These errors occur only the first time that I try to call a WebReport using a Parameter Form from a WebForm.
On the Forms/Reports 10g running on my LinuxServer under iAS, the right hand side Fields for my Parameter Form Parameters are missing, for parameters of type Character + I cannot call-up my WebReports.
YOur feedback is appreciated......

PS: I tried to make modifications to the rwservlet.conf and the repsrv.conf and the rep_Linux2005.conf files without success.
