[ST2 PR3] Store filterBy error when the store has just one item.

[jwjiwon]

Thanks, Mitchellsimoens,
Actually the one I wrote down previously was happened in the middle of report THIS bug.

When I use a filterBy function, it keeps giving me the below message
Uncaught TypeError: Cannot call method 'addCls' of null
and I found out that when the list is filtered until the number of list item becomes just one,
the message show up.

I use the google Chrome 16, and here's the code I reorganized for you.

Ext.application({
  name: 'Joy',
    
  launch: function(){
    
    var container = Ext.create('Ext.Container', {
        fullscreen: true,
        layout: 'fit',
        items:[
       {
            xtype: 'toolbar',
            dock: 'top',
            title:  'JOY',
            items: [{
                xtype: 'searchfield',
                id: 'searchTopicField',
                placeHolder : 'Topic',
                border: '1',
                width: '99%',
                margin: '5',
                listeners: {
                        
                  keyup : function( textField, event, options ){
                                
                    var searchList = container.getComponent('searchTopicList'),
                    textValue = textField.getValue(),
                    searchListStore = searchList.getStore();
                                
                    console.log(textValue);
                    if(textValue.length > 0){
                
                      searchList.setHidden(false);
                            
                      var find = false, firstRecord;
                                    
                      searchList.getStore().filterBy(function(record){
                        fieldData = record.data.topic.toLowerCase().indexOf(textValue);
                        if(fieldData > -1){
                            return record;
                        }
                      }); 
                                    
                    }else{
                                    
                        if(searchListStore.isFiltered()){
                            searchListStore.clearFilter();

I tried this and got not error:

var list  = container.down('list'),
    store = list.getStore();

store.filterBy(function(rec) {
  return /education/i.test(rec.get('bigtopic'));
});

I tried this and got an error:
which has just one item when it was filtered.

var list = container.down('list'), store = list.getStore();store.filterBy(function(rec) 
{ return /economics/i.test(rec.get('bigtopic'));});

[mitchellsimoens]

And what was the error as I got no errors.

Ok, that one is an open bug when there is only one item in the group.

[jwjiwon]

please make it [OPEN]

[mitchellsimoens]

There is already a bug open. I'm not going to open two for the same thing.

[jwjiwon]

I said it because the title of this thread is still 'closed'.
Anyway, you said open so it is open
