    I just moved to the latest CVS to work on the hsql stuff and I am all
    of a sudden getting an exception at this block of code whenever I
    prefetch a to-one relationship:

            if (incoming.isToMany()) {
                ToManyList toManyList = (ToManyList) object.readProperty(getName());

                // TODO, Andrus 11/15/2005 - if list is modified,
    shouldn't we attempt to
                // merge the changes instead of overwriting?
                toManyList.setObjectList(related != null ? related : new
    ArrayList(1));
            }
            else {
                // this should've been handled earlier in 'linkToParent'
                throw new CayenneRuntimeException(
                        "To-one relationship wasn't handled properly: " +
    incoming.getName());
            }

    It could certainly be a problem with my map that wasn't being exposed
    until now. I haven't had time to dig into it yet, but its definitely
    something that started happening between M7 and now. Considering the
    prefetch work, I thought I'd point it out.
