Filter grid feature is broken for buffered grids

[zerkms]

Ext version tested:

• Ext 4.1.1 RC2

Description:

• If filtered result fetches the store cache completely - the store won't ever request new data, because it assumes all the data fetches the cache and no reason to perform further requests:

Part of related code from store.js:

    prefetchPage: function(page, options) {
        var me = this,
            pageSize = me.pageSize || me.defaultPageSize,
            start = (page - 1) * me.pageSize,
            total = me.totalCount;


        // No more data to prefetch.
        // (comment from zerkms: this condition will always evaluate to true if result set is small)
        if (total !== undefined && me.getCount() === total) { <------ !!!!
            return;
        }


        // Copy options into a new object so as not to mutate passed in objects
        me.prefetch(Ext.applyIf({
            page     : page,
            start    : start,
            limit    : pageSize
        }, options));
    },

Steps to reproduce the problem:

• Take http://dev.sencha.com/deploy/ext-4.1...ter-local.html
• Set up server-side part
• In the grid-filter-local.js change:
  • var local = true; to var local = false;
  • Append buffered: true attribute to the store object (right after `pageSize: 50`)
• Load the modified example
• Try to filter by company name

The result that was expected:

• The grid should be filtered

The result that occurs instead:

• The "Loading..." throbber will spin infinitely and the grid is locked

The latest code has

        if (me.remoteFilter) {
            // adding a filter will almost always change the total count
            delete me.totalCount;

in the filter method, so this should be fixed.

When you say "latest" you mean svn?

[Animal]

Well, github, but yes, the latest code which is to be released soon.

Oh.... We have access to svn, but how can we access sencha's github? ;-)
