Flex Mobile Project: List

Question

I am developing a mobile application in which I want to use a list which contains 400 rows. I got data from Sqlite database. When I run the application and click the button for the list, the list view is loading so slowly and takes about 45 seconds. I also tried getting data from an arraycollection inside the application but I had same problem. Is this normal? Any idea or advice for this issue?

                    sqlStat.text="SELECT City FROM Cities";
                    sqlStat.execute();
                    dataArray=sqlStat.getResult().data;

                    appModel=AppModel.getInstance();

                    if(appModel.cities == null)
                    {
                        appModel.cities = new ArrayCollection();
                        var obj:Object;
                        for( var i:int=0; i<dataArray.length; i++ )
                        {
                            obj = new Object();
                            obj.Name = dataArray[i].City

                            appModel.cities.addItem(obj);

                        }
                    myList.dataProvider=appModel.cities;    
                    }

I solved my problem. ListForm component causes renderer problem. I used List component instead of that and created arrayCollection dataprovider for my list inside my class. It works faster than previous.
