(Warning) Objects for binding must implement IComparable interface

[vlkam]

Otherwise, bindings don't work

Solution : comment line ((v is IComparable) && ((IComparable)v).CompareTo(Value) != 0))

in method

void OnSideChanged(Expression expr, Expression dependentExpr, int causeChangeId)

Ah yes I should use equality comparison.
