    Hi

    I have a simple one-to-many relationship : AppleTree - Apple. I'm
    doing a query :
    new SelectQuery(AppleTree.class, expression)
    how should the expression look like to return the trees with apples ?
    expression = ExpressionFactory.noMatchExp(AppleTree.APPLES, null)
    does not seem to work, neither does
    expression = ExpressionFactory.noMatchExp("applesArray", null)

    Regards
    Marcin
