Qt Contacts 5.0 Filter: Unable to assign int to [unknown property type]

Hi All

I am experimenting with QtContacts 5.0 on SailfishOS using QML
.
However things go pear-shaped when I try and filter the contacts:

I get the error:
file:///usr/share/ContactsDemo/qml/pages/FirstPage.qml:62: Unable to assign int to
[unknown property type]

This refers to the detail: ContactDetail.Name of the Filter, even though it was able to
use an identical property to sort.

Having delved into the source of QDeclarativeContactSortOrder and
QDeclarativeContactDetailFilter, I see that the first declares detail to be of type int,
but the second declares detail to be QDeclarativeContactDetail::DetailType

class QDeclarativeContactSortOrder :public QObject, public QQmlParserStatus
{
Q_OBJECT
Q_PROPERTY(int detail READ detail WRITE setDetail NOTIFY sortOrderChanged)

class QDeclarativeContactDetailFilter : public QDeclarativeContactFilter, public
QQmlParserStatus
{
Q_OBJECT
Q_PROPERTY(QDeclarativeContactDetail::DetailType detail READ detail WRITE setDetail
NOTIFY valueChanged())

However I have got no further in figuring out what I am doing wrong / what is going wrong.

Something very similar to the code below works on Harmattan./Qt 4.7.4 /Qt Mobility Contacts: On Harmattan Filtering works for Name.firstName and Name.lastName, but not for DisplayLabel.Label (see https://bugreports.qt-project.org/browse/QTBUG-35259). In fact I was trying to reproduce the DisplayLabel filter problem on Qt5.0 when I found that I cannot filter at all....

Any ideas?

Thanks

Chris
