New item can't display in ListView.

[useryy2]

When adding a new item in the ListView from UI, the item's name can't display.
But if I flick on the ListView up and down, the name comes.

Meantime, in delegate module, it says. "Unable to assign [undefined] to QString text" where "text" should display the item's “name"

This is why? How to display it automatically?

I've tried the sync() method of ListMode, but doesn't work.

 Rectangle {
     color: "white"
     width: 200
     height: 300

     ListModel {
         id: fruitModel
         ListElement {
             name: "Apple"
             cost: 2.45
         }
     }

     ListView {
         anchors.fill: parent
         model: fruitModel
         delegate: Component {
             ...
         }

         ListModel { id: listModel }
     }
 }

Adding item from UI means adding it from c++ or else? Also can you show how do you add the item

i will be also interested to see your code of delegate implementation.

If I add anything into the list model, list is automatically updated.

check for: ListModel::append ( jsobject dict )

are you doing something different?

Basic code implementation is from "QtSDK\Examples\4.7\declarative\modelviews\listview\dynamiclist"

And I have found the reason:
When adding a ListElement , I will
1) Create a new ListElement in Javascript.
2) Insert/Append it.
3) Update the element's "name"/"cost"

As a result, in step 2, the UI changes. But for step 3, UI does not update.

To workaround:
1) Create an empty ListElement when the ListView is first created.
2) Change the ListElement's "name" or "cost" according to input from UI
3) Create a new empty ListElement Javascript.
4) Append/Insert it for next round.
