    Hello,

    is there a nice way to sort a List of Cayenne-Objects on o
    primary-key-field, e.g. "id" (pk) in memory, because the user can resort
    the existing list more than one time. I don't want to read it out from DB
    every time.
    This doesn't help:
            this.resultList = new ArrayList(this.resultList);
            Ordering ordering = new Ordering("id", true);
            ordering.orderList(this.resultList);
    In this example the ordering is not correct or will not be changed.

    Can anyone help with this...or have a better idea...

    Thank you
    Zvonimir
