Hi,
I have a canvas mail app, where i have To:\ Cc:\ Bcc:\
I have a To:\ combo box , the defaultselectedItems value is below.

When i select the below , i am getting empty record, which means it is not recognizing the value from the 'default selected item'.

But when i remove the default selected item , and manually go and select a email from a drop down, it is sending the email successfully to the person in To:
What is the wrong with picking the default selected item?
Just for understanding , here is my Sample canvas app
