WPFProperty not supported by the object

WPFProperty not supported by the object

Dear all,
I have encountered a problem with the WPF element which was described at Copa Data blog: http://blog.copadata.at/wp/?p=38. I have all the assemblies and when I put a wpf element and link it to chart.xaml file on the screen in editor it is loaded, however when I start runtime the wpf element is not visible at all!!!
When I run my VBA script in debugmode:
VBA Code:

Public Sub PassDataDirect()
Dim obElement As Element
Set obElement = thisProject.DynPictures.Item("Start").Elements.Item("elem")

If IsEmpty(obElement) Then MsgBox "no"
obElement.WPFProperty("Chart1", "ValueName") = "intern1"
obElement.WPFProperty("Chart1", "Value") = thisProject.Variables.Item("intern1").Value
obElement.WPFProperty("Chart1", "AddValue") = True
End Sub

I get an error: runtime error 438, object doesn't support this property or method at the lines with WPFProperty. What is the reason for that? It is not shown during runtime operation though.
Thanks for your help
