Returning more attributes in search set when inviting to new event

Question

Hi all,
We are currently running SunOne Calendar 5.1 and some of our users are complaining that when inviting people to an event who have a common name (i.e. John Smith), quite often, more than one result is displayed in the search set. With two "John Smiths" who have no middle name, how do you determine who the correct person is you wish to invite?
Is there any way of displaying other attributes in the search set (i.e. e-mail address), so users can select the correct person?

I have found a solution to this issue. It seems that when using a programmatic view object which has a transient attribute as its primary key you need to override more methods in the ViewObjectImpl so that it knows how to locate the row related to the primary key when the view object records aren't in the cache. This is why it would work correctly sometimes but not all the time. Below are the additional methods you need to override. The logic you use in retrieveByKey would be on a view object by view object basis and would be different if you had a primary key which consisted of more than one attribute.
@Override
protected Row[] retrieveByKey (ViewRowSetImpl viewRowSetImpl, Key key, int i) {
    return retrieveByKey(viewRowSetImpl, null, key, i, false);
@Override
protected Row[] retrieveByKey (ViewRowSetImpl viewRowSetImpl, String string, Key key, int i, boolean b) {
    RowSetIterator usersRowSetIterator = this.createRowSet(null);
    Row[] userRows = usersRowSetIterator.getFilteredRows("UserId", key.getAttribute(this.getAttributeIndexOf("UserId")));
    usersRowSetIterator.closeRowSetIterator();
    return userRows;
@Override
protected Row[] retrieveByKey (ViewRowSetImpl viewRowSetImpl, Key key, int i, boolean b) {
    return retrieveByKey(viewRowSetImpl, null, key, i, b);
