Tell us about the problem

I have a list view, and this list view has a label (per item of course) that I hide using a converter, if the property bound to the Visibility is Null the console throws the warning:
"JS: Binding: Binding error while setting property visibility of Label(17)@file:///app/main-page.xml:9:17;: Error: Invalid value null for property visibility"
I think it was ok with NS 2.0.0 btw.
