[Interest] Updating a qml tableview model from a combo box delegate having a model

[John Plummer]

     No doubt this is a simple fix but I could not find any examples.  I 
have a Tableview defined in a qml
file.  It is being 'sourced' several times from a view qml script and 
passed a QObjectList model.
     Everything displays fine and the TableViewColumns update the model 
fine except for those with
a ComboBox delegate.  Here's a code snippet showing the problem area:
TableView{

id:oetableview

     ....

TableViewColumn{

role:"pieces";

title:"Pieces";

width:50;

delegate:Item{

SpinBox{

id:currentPieces;

anchors.verticalCenter:parent.verticalCenter;

//decimals:2;

value:styleData.value;

width:parent.width

onEditingFinished:model.pieces=currentPieces.value.toString();

}

}

}

     TableViewColumn{
         role: "invoice_type"  ;
         title: "Inv Type" ;
         width: 100 ;
         delegate: Item {
             ComboBox {
                 id: invoiceTypeCombo
                 width: 100
                 model: categoryModel
                 currentIndex: categoryModel.indexOf(styleData.value)
                 onActivated: {
                     model.invoice_type = invoiceTypeCombo.textAt(currentIndex)
                     console.log("Activated " + invoiceTypeCombo.textAt(currentIndex) + " " + styleData.value)
                 }
             }
         }
     }
    ....

     The model has identical set's for both roles:

void OEObject::setPieces(const QString &pieces)
{
     if (pieces != m_pieces) {
         m_pieces = pieces;
         emit piecesChanged();
     }
}

void OEObject::setInvoice_type(const QString &invoice_type)
{
     if (invoice_type != m_invoice_type) {
         m_invoice_type = invoice_type;
         emit invoice_typeChanged();
     }
}
    
    The problem appears to be model.'role' = statement.  The spinbox updates fine but the combobox does not.  I'm
thinking the the combobox does work since the delegate has a model also.  (The categoryModel is from C++ and is
used to populate the comboboxes only.)  I've tried qualifying the model in the model.'role' statement but have
not found one that works.  The log shows the correct value is there for assignment.
    Does anyone have any suggestions?  Thanks in advance.
    Completely unrelated.  I noticed that hovering over a spinbox allows the user to change its value without
giving it focus.  This way of changing it does not fire the onEditingFinished unless the user clicks on the field.
Is this expected behavior?
