[4.2.0.489] buffered store, loading not completed

[user ext]

If in 'Infifnite Grid' example (see Ext JS 4.2.0 - Sencha Docs ) set for the store
pageSize: 10
the loading is not completed.

To avoid this:

 loadToPrefetch: function (options)
 {
  ...
 
  
     if ((dataSetSize = me.getTotalCount())) {
 
     // Wait for the requested range to become available in the page map
    me.data.on('pageAdded', waitForRequestedRange);
 
     // As soon as we have the size of the dataset, ensure we are not waiting for more than can ever arrive,
    // And make sure we never ask for pages beyond the end of the dataset.
    loadEndIdx = Math.min(loadEndIdx, dataSetSize - 1);
    endPage = me.getPageFromRecordIndex(loadEndIdx);
 
      if (me.data.maxSize < endPage - startPage + 1) { me.data.maxSize = endPage - startPage + 1; }
  
    for (i = startPage + 1; i <= endPage; ++i) {
          me.prefetchPage(i, prefetchOptions);
    }
 
   ...
 
   }

In this case you'll need to alter the purgePageCount.
