[Saxondotnet-devcommunity] problem with XPathExpression class?

[Andrew S. <and...@ya...>]

Hi everyone,

I am using Saxondotnet in a test VB.NET project.  In
the action of a button-click I have:

Dim inputFile As New java.io.File(<any-xml-file>)
Dim inputSource As New StreamSource(inputFile)
Dim evaluator As New XPathEvaluator
Dim expr As XPathExpression =
evaluator.createExpression("/*")
Dim ret As Object = expr.evaluateSingle(inputSource)

The last line throws the following exception:

System.TypeLoadException was unhandled
Message="Method
'java.lang.Comparable/compareTo(Ljava.lang.Object;)I'
on type 'net.sf.saxon.value.CalendarValue' from
assembly 'Saxon.NET, Version=0.2.8.3, Culture=neutral,
PublicKeyToken=039082bc3d203ffd' is overriding a
method that has been overridden."
Source="Saxon.NET"
TypeName="net.sf.saxon.value.CalendarValue"
StackTrace:

source)
       at
WindowsApplication1.Form1.Button1_Click(Object sender,
EventArgs e) in WindowsApplication1\Form1.vb:line 17

Should this be?  Is this a bug?  Any suggested
workaround?

Thanks for any replies as well as all your hard work
on SaxonDotnet.  It is really appreciated,

Andrew
