QML Contact model search crash

[Vaibhav.sood15]

What I have is a listview, to show list of contacts. There is one model for that listview, a search box and also a label. Whenever the user enters text in the search box, to filter the contacts based on the text typed in the search box.


Here is my code

// import QtQuick 1.0 // to target S60 5th Edition or Maemo 5
import QtQuick 1.1
import Qt 4.7
import QtMobility.contacts 1.1
 
Rectangle {
    property QtObject blah: con
    width: 360
    height: 640
 
    ListView
    {
        anchors.top:searchbox.bottom
 
height: parent.height
width: parent.width
        id: _ListViews
 
        model:ContactModel{
 
           filter:  DetailFilter {
 
               id:filter
 
               detail:ContactDetail.Name
 
               field:Name.FirstName
 
               value:searchbox.searchtext
               matchFlags:Filter.MatchStartsWith
 
            }
           sortOrders: SortOrder{
               detail: ContactDetail.Name
               field:Name.FirstName
               direction: Qt.AscendingOrder
 
           }
}
 
        delegate: Rectangle{
            width: parent.width
            height:50
            Item {
                Column{
 
                    Text {
            id: name
            text:  model.contact.displayLabel
                    }
                }
            }
 
        }
    }
   SearchBox{
       id: searchbox
 
           visible: true
 
 
}
 
 
}

// import QtQuick 1.0 // to target S60 5th Edition or Maemo 5
import QtQuick 1.1
import Qt 4.7
import QtMobility.contacts 1.1

Rectangle {
    property QtObject blah: con
    width: 360
    height: 640

    ListView
    {
        anchors.top:searchbox.bottom

height: parent.height
width: parent.width
        id: _ListViews

        model:ContactModel{

           filter:  DetailFilter {

               id:filter

               detail:ContactDetail.Name

               field:Name.FirstName

               value:searchbox.searchtext
               matchFlags:Filter.MatchStartsWith

            }
           sortOrders: SortOrder{
               detail: ContactDetail.Name
               field:Name.FirstName
               direction: Qt.AscendingOrder

           }
}

        delegate: Rectangle{
            width: parent.width
            height:50
            Item {
                Column{

                    Text {
            id: name
            text:  model.contact.displayLabel
                    }
                }
            }

        }
    }
   SearchBox{
       id: searchbox

           visible: true


}


}

To copy to clipboard, switch view to plain text mode 

whenever i type a letter i get the error

TypeError: Result of expression 'model.contact' [undefined] is not an object.

if there are no matches in the contact list the app crashes



Now I need to display nothing found in the list view, when there are no matches in the list. How to achieve that.?

I have a similar issue like Vaibhav.sood15. I can filter contacts based on the text typed in the search box. But if there are no matches in the contact list the app crashes and terminates. I have posted a question with my code in stackoverflow. Here is the link. http://stackoverflow.com/questions/1...el-has-no-data

Hi can you send me your complete proj so i can see if you are getting errors while filtering everytime or just once when the app crashes.

Just hav a look at the stackoverflow link. I have pasted my whole code there. And yes, I can filter contacts everytime based on the text typed in the searchbox, without any errors. Only if there was no matches, the app crashes.

Did you try it on the simulator or a real device coz mine crashes on the simulator not on a device

I tried it with a Symbian belle device. ( Nokia N8 ).
