   Apologies for arriving late to this issue.  Can someone explain the need for conditionalBind() and when it would be used?  The issue from looking over the source (I haven't debugged into it), is that expressions like `parentApplication.buttonFunction;` must be strongly typed.  Properties that are of type `Object` or `*` like `parentApplication` cause the compiler to lose track of the types of things so the code paths you want in the transpiler don't get hit.  The correct code would look more like:
   
   `(parentApplication as Example).buttonFunction;`
