I have error on button event property

[Daniel Stoilkov]

I have created event for my LogOut button i set it when someone click on it to change the value of the horizontal slider switch to false, in the property value field I enter 1 or 0 but don't wont to accept it accept only true/false I say that is OK . But when I run my application and press the button I have  error.  I attached picture of the error .

And I have this error not all the time, just few times.

The real strings should be "True" and "False". We are supposed to support all lowercase also, but perhaps that isn't completely working. Capitalize the first letter and see if that helps.
