Issue with custom node style and Expression blend 4

Hello!

I have a diagram surface and several custom styles for diagram nodes. I've got the following exception when i tried to edit the style in expression blend 4: Unable to cast object of type System.String to IDiagramNode. Please check the attachement. There is a full call stack.

<Style x:Key="node1Style" TargetType="{x:Type ms:DiagramNodeElement}">
            <Setter Property="NodeTemplate">
                <Setter.Value>
                    <DataTemplate>
                        <Grid>

                        </Grid>
                    </DataTemplate>
                </Setter.Value>
            </Setter>
    </Style>

Thanks in advance.

Hello and thanks for the feedback. We will get back to you very shortly.

Hello

Thanks for pointing this out and sending the call stack. I'm not sure why the content was being set as a string, but I have fixed this for the DiagramNodeElement to handle this without causing the exception. The candidate fix for this will be available through the next nightly build (available at around 1200 GMT). Nightly builds can be downloaded from here: http://www.mindscapehq.com/products/wpfdiagrams/nightly-builds

Let us know how it goes.
