Store doesn't refresh totalCount after adding data

Hey together,

I have a memorystore.

In the beginning everything is working fine.

If i add a record to the store by oStore.add(data), the paging doesn't get the new pagenumber. If i change the page, the new added record is lost.

after adding the record, the store does not change its totalCount, so the paging doesn't know, there is a new page.

If i use a pagingmemory Store nothing works anymore.

Has somebody an example for adding things to a memoryStore I can look at?

Thanks!

Here is the konfiguration of my store:

Code:

     
 oStore = Ext.create('Ext.data.Store', {         model: strModel,
         success: function(strResult,oDataObject){
            // only called when using proxy
            Ext.log({level:'debug',dump:oDataObject},"createSelectedItemsStore create success"+strResult);
         },
         pageSize: nItemsPerPage,
         proxy: {
            type: 'memory',
            enablePaging: true
         },
         listeners: {
            load: {
               fn: function(store,data){
//                  console.debug("createSelectedItemsStore listeners load",store,data);
               }
            }
         },
         data: aData
      } );
