Problem importing data from Voson

Feb 15, 2012 at 8:14 PM

Hi, I was trying to import Voson data into nodeXL, when I received the following error message.

[ArgumentNullException]: Smrf.NodeXL.Adapters.GraphMLGraphAdapter.LoadGraph: theString argument can't be null.

Parameter name: theString

 

 

   at Smrf.AppLib.ArgumentChecker.CheckArgumentNotNull(String sMethodName, String sArgumentName, Object oArgumentValue)

   at Smrf.NodeXL.Adapters.GraphAdapterBase.LoadGraphFromString(String theString)

   at Smrf.NodeXL.ExcelTemplate.ThisWorkbook.ImportFromGraphDataProvider(IGraphDataProvider graphDataProvider)

 

I have retried this process twice and continue to receive this message. Is there some way to troubleshoot this issue?

 

Thanks

This is a question for the VOSON developers.  I found this link at http://voson.anu.edu.au/node/19:

"For assistance with the VOSON System or VOSON+NodeXL please email support@uberlink.com.au (please quote your account username)."

...and you can point them to this page, http://nodexl.codeplex.com/discussions/316945, for details.  The technical problem is that the VOSON graph data provider is returning a null string to NodeXL, which is illegal.
