When deploying a K2 (Blackpoint or Blackpearl) Infopath Integrated Process you may get an error similar to:

Server was unable to process request. —> Specified argument was out of the range of valid values.
Parameter name: value

Not sure what causes the error but the quickest way round it seems to be to delete the form library & recreate it. Your K2 process will now delpoy with no problems. (Well in my case it does!)

FYI Neither K2 Blackpoint or K2 Blackpearl support SSO, they only support Windows authentication. K2 Connect (SAP) makes use of SSO in some aspects.

If you are trying to use in an SSO environment you will see errors similar to:

Unable to cast object of type ‘System.Web.Security.SingleSignOn.SingleSignOnIdentity’ to type ‘System.Security.Principal.WindowsIdentity’

Update: Apparently Blackpearl users can create a custom security provider to handle SSO authentication.

• Known Issues With K2 Blackpoint

Go to “Software\Microsoft\Windows\CurrentVersion\App Paths\InfoPath.exe” in your registry (if infopath.exe does not exist create it), there you will see a “Path” value if you do not then create a new string value with the the name “Path” and in the “Value Data” portion add the path to the infopath exe folder, for example, “C:\Program Files (x86)\Microsoft Office\Office12\

Also in the ‘Default’ string add the path with the actual filename ie. “C:\Program Files (x86)\Microsoft Office\Office12\infopath.exe”

Now close K2 designer & reopen, you will now be able to edit Infopath forms from within K2

Well I read numerous posts etc but nothing definitive, after speaking to K2 basically there are ‘some’ issues running K2 Blackpoint in a HTTPS environment however full SSL support will be introduced in 4.5 release for both K2 Blackpoint & K2 Blackpearl. A formal release date has not been set but they are looking at the end of Q1 2010.

Hope this helps anybody looking into this & hopefully not long to wait !
