Aside from the semantic errors (e.g., derefencing a variable called
'selection' when it has not been defined nor initialized), the big problem
is that you're using the mixin from within the constructor, where the
mixin's constructor hasn't yet been called. A mixin's constructor is called
after the constructor of the class that includes it.
Here's a modified test class that also puts member functions into the
members section where they really ought to go, unless there's some really
good reason for assigning them in the constructor.
Hope this helps,
