BUG: Passing in existing state for a field of type double is not working

In C# see below:

//update the initial state before calling dialog
var state = new MyDialog();

state.StringItem = someString; //this string gets copied into the called dialog
state.StringItem2 = someString2; //this string gets copied into the called dialog
state.DoubleItem = doubleVal; //this double DOES NOT get copied into the called dialog and i am prompted to enter it in the dialog

context.Call(new FormDialog<MyDialog>(state, MyDialog.BuildForm, options: FormOptions.PromptInStart), null);

neither of the following assignment substitutions work either:

state.DoubleItem = 99; //doesn't work
state.DoubleItem = 99d; //nor does this

This is by design. We have no idea whether or not there is a value in your field–how do we know 0.0 is no value, but 1.0 is a value? If you change your double to be a nullable field then we can distinguish and it will be skipped if you supply a value.

I figured it out right when you posted your reply and after hunting down that chunk of code. Changed my field from a double to a double? and naturally it works. Thanks!
