Data Binding bug with OfficeSilver

 I've been tripping on what seems to be a theme-induced data binding bug.  It took me a couple days to get where I could reproduce this and then to isolate it down to a theme bug.  In the attached project, there's probably a bit more that could be stripped out, but it's all canned data and just a handful of data classes.  The UI is stripped down to basically just a couple ListBoxes and a ComboBox.  To see the bug do the following:

Build and run the project.
Click on the ChangeDimensionDummy
Pull down the combo to the right and select "grimble".  If you've got the Output window open in the debugger, you'll see "set Ref=grimble".
Click on the lower ChangeListenerDummy in the upper ListBox.
Click back on the upper ChangeListenerDummy.  Note that grimble is still in the ComboBox.
Click again on the lower ChangeListenerDummy.  Note in the Output window you'll see "set Ref=".  That's the bug.
Now click back on the upper ChangeListenerDummy and you'll see that the contents of the Combo are cleared.

Comment out the reference to OfficeSilver in the Window1.xaml file and you'll see the problem goes away.

Hello kdonn

Thanks for finding this issue. I have fixed the problem across all the themes and it will be available in the nightly builds from tomorrow the 20th of November.

Or if you want to have the fix right now, simply remove the following code snippet from line 713 of the OfficeSilver theme:

Text="{TemplateBinding SelectedValue}"

Regards
