Cannot access list on an object from a slot

I have a slot in QML where i receive several QObjects, one of them is DataServicePage.

This object has a QList<DataServiceBox*> as well as a QString id.

To access both from QML i use Q_PROPERTY:


Q_PROPERTY(QString id READ getPageId)
Q_PROPERTY(QDeclarativeListProperty<DataServiceBox> boxes READ getDataServiceBoxesQml)

In QML i can access the id property successfully and get the value of the QString.

However, when i try to access the boxes property i get this (created by:  console.log("page boxes: " + page.boxes) ):

page boxes: QVariant(QDeclarativeListProperty<DataServiceBox>)

when i try to access the length attribute i just get "undefined" though.


I use this construct successfully when i access the base object (that contains the list) from a context property, but the exact same code does not work when the base object comes in a slot.

When it works (in the other cases) i get a different console output, just [object Object] instead of QVariant


Is it possible that the slot mechanism somehow does not work with the list property?
