Getting error while submitting data to excel workbook through excel services in InfoPath 2010

Question

Hi,
I have a requirement where in have to fetch the calculated values from the excel workbook through InfoPath 2010 form.
When I am submitting cell value to excel workbook using SetCellA1 by executing following action:
"Submit using data connection: dataconnection"
I am unable to submit form. It is giving "there has been an error while processing the form" in the front end. I checked the event viewer and it displayed following exception:
There was a form postback error. (User: xxxx, Form Name: yyyyyyyy, IP: , Request:
http://asadadsas Request Form Template.xsn&SaveLocation=/somelocation, Form ID: urn:schemas-microsoft-com:office:infopath:formname:-myXSD-2010-09-20T15-02-34, Type: KeyNotFoundException, Exception Message: The given key was
not present in the dictionary.)
I was successfully able to submit the form using InfoPath client but it is giving error in the browser.
Is there any way or configuration that I should do to resolve this issue.
Any suggesttion would be of great help.
Thanks,

I have exactly the same problem. The form is supposed to be submitted to the SOAP Web service (http://servername/_vti_bin/ExcelService.asmx) using the SetCellA1 operation, works fine in InfoPath Filler, but when I try to submit it in the browser, I get this
error:
There was a form postback error.

What might be wrong? Are there any InfoPath configurations that need to be done? And, do I need to save the connection to the Excel Service Service Application to a connection file?
