    If I understand what you're asking, yes. The ExpressionFactory will do the
    right thing if you give it a value of null.

       Expression notNullExp = ExpressionFactory.noMatchExp("attributeName",
    null));

    Subject: Testing ExpressionFactory for null values

    Is it possible to test for null values using the in-memory
    ExpressionFactory?

    Or is it just bad design to keep default values as null?
    Does anyone have any input?

    Thanks!
