      Hi all,

      from QML I'm trying to get a list of QObject, invoking a Slot. It works only if a instance variable is used to store the list.

       

      For example, the following code works well (it returns a well-formed list of TestModel to QML):

       

      @Slot(result='QVariantList')
def working_get_all(self):
    self._entries = []
    for i in range(5):
        model = TestModel()
        model.name = 'Name ' + str(i)
        model.description = 'Description ' + str(i)
        self._entries.append(model)
    return self._entries

       

       

      while the following code returns a list of null:

      @Slot(result='QVariantList')
def not_working_get_all(self):
    entries = []
    for i in range(5):
        model = TestModel()
        model.name = 'Name ' + str(i)
        model.description = 'Description ' + str(i)
        entries.append(model)
    return entries

       

      As attachment there is a complete example for bug reproduction.
