    Hi,
    I'm doing an application using ModelContact of QML. I get modelContact.contacts[i].contactId in an array.
    So I try to delete every Contact from array.

    @
    for(var i =0;i<JsModels.repeated.length;i++)
    modelContacts.removeContact(JsModels.repeated[i])
    @

    But it doesn't remove the contact. But if I do:

    @
    modelContacts.removeContact(400)
    @
    with a const number the function does remove.

    Does anybody know how I could fixe this problem?

    Thanks,
    Fernando Moreno.

      Presumably we're actually working with ContactModel, http://doc.qt.nokia.com/qtmobility/qml-contactmodel.html

      I would say the problem here is that the values in the JsModels.repeated array are nonexistent or invalid. If I were you, I would try this:
      @
      for(var i =0;i<JsModels.repeated.length;i++) {
      console.log("Removing contact ID " + JsModels.repeated[i])
      modelContacts.removeContact(JsModels.repeated[i])
      }
      @
      See what it's actually trying to remove.

        Hi,
        thanks for reply.
        Yes I did and I saw correct values. But it looks like the removeContact function don't allow this type of value. Just const int works. I think the type that I store in array is QContactId or something like that. And I cannot convert this type to const int.

        Best,
        Fernando.

          If the console.log() line works, then obviously the array values can be interpreted as a string. If the string contains a number, we can work with that like so:
          @modelContacts.removeContact(Number(JsModels.repeated[i]))@
          Give that a whirl and see if it works.

            Hi,
            It doesn't work yet.

            Thanks.

              http://www.macieira.org/blog/2012/05/doesnt-work-doesnt-work/
              Just saying... ;)

              I'm assuming there are no errors... I'm not entirely familiar with the Number function, so let's try parseInt instead:
              @modelContacts.removeContact(parseInt(JsModels.repeated[i]), 10)@

              And where does JsModels come from, anyways?

                I have to try the suggested sentece. JsModels is a "model" created by me to perform jsons using.

                Best,
                Fernando.
