ComboBox does not support object array

ComboBox ‘s data model don't support object array
such as [

{display:"a",value:0}

,

{display:"b",value:1}

]

because Combobox.qml source code delegate is

delegate: ItemDelegate

{ width: control.width text: control.textRole ? model[control.textRole] : modelData checkable: true autoExclusive: true checked: control.currentIndex === index highlighted: control.highlightedIndex === index pressed: highlighted && control.pressed }

I suggest that
change text for example: Array.isArray(model) ? modelData[textRole] : model[textRole]

textRole is empty text is modelData.
