InfoPath Dev

Hi:

 I build an Infopath template by Visual Studio 2008, and publish it on MOSS 2007 successfully. The form is Full Trusted. I have Infopath Client installed on this server.

Also I create an Infopath form library which I can creat or edit Infopath form by MS Infopath. But if I create in brower and trying to save it, it shows warning as below:

Unexpected end of file while parsing Name has occurred. Line 1, position 844.

System.Xml.XmlException: Unexpected end of file while parsing Name has occurred. Line 1, position 844.

Could anyone give some suggestion on that?

Thanks!

I debug this form on MOSS which has Infopath Form Service installed, but it is not error or exception thrown by my code.

It happened when I Save the form. I am not sure whether it is due to some feature not supported by IF service.

Hope you can give some hint.

Thanks
