Where I create 2nd object? T*Editor is just descendant of TForm (it's more complicated structure, but base class for any editor is TForm) where I have controls to edit layer
I did that I set values in editor contructor.
But I still don't understand why this value is zero? Before constructor is ok, in constructor is ok, after constructor is not ok... (only this field is bad, fields from previous classes are ok at all).
