Hi Luis,

You can get a more informative error from infopath if you choose to have it opened using infopath thick client rather tan web client, then when you open the form the error will have a show details button.

If you are using K2 studio to deploy the process then in the infopath integration wizard there is a drop down that lets you specify thick client, or web browser. Change this and redploy and retry.

I tried your suggestion and the form works fine using the thick client. Any ideas?

Ok it could be an authentication issue, perhaps credentials are being lost. What is the environment you are in? Depending on your logging configuration if you look in

 C:Program Files (x86)K2 blackpearlHost ServerBin

there will be a log file called HostServer xxxxxx_x.log you can open this up and see if there are any errors at the time of your submit.

to configure logging open HostServerLogging.config and chalge this node <LogLocation Name="FileExtension" Active="True" LogLevel="Error" /> to LogLevel of "Debug" save and then restart the K2 server (windows service) this will give you a more verbose level of logging

Also with the form running through form serviecs you can check the sharePoint Logs ffor errors

in 2007 its

C:Program FilesCommon FilesMicrosoft SharedWeb Server Extensions12LOGS

in 2010 it will be similar but in the 14 rather than 12 root

did the user have enought permission on workflow and the list.

Updating the server to the latest version of K2 solved the problem.

thanks,

Luis
