deploy error

[Fred]

I have deploy a form to form server with unknown error, so I go to the
Program Files\Common Files\Microsoft Shared\web server extensions
\12\LOGS, and find some error info like below,

TryRunConversion failed with unhandled exception
System.NullReferenceException: Object reference not set to an instance
of an object. at
Microsoft.Office.InfoPath.Server.Converter.RoundtripModelDetectionVisitor.VisitInfoPathControl(AspxInfoPathControl

control) at
Microsoft.Office.InfoPath.Server.Converter.AspxDepthFirstWalkingVisitor.VisitControl(AspxControl
control) at
Microsoft.Office.InfoPath.Server.Converter.AspxDepthFirstWalki...

This form has been deployed before, and I just upgrade the schema with
two additional fields. I tried to remove the old form and add the new
form, but it still can not go through, is there anyone who has the
same problem before?

Thanks

Hi Fred,

There are a number of reasons this could have happened - most of them
difficult to diagnose unfortunately. You could try some of the following:

- Try and do a "Verify" instead of a straight publish. Sometimes I get
proper errors doing this.
- Are there any references you have added to code-behind? If Forms Services
can't compile your .NET code you could get this error
- Your upload may be timing out. I have got this error when the form is
quite large (lots of views, complex code, etc.). You might need to simplify
your form (ugh) or try a reboot and see if it works then. Sometimes my SQL
server instances hog RAM and it seems to use a lot during form publishing.
Use Task Manager to check resources, and be shocked at the amount of RAM/CPU
a form publish uses

HTH

Gavin.
