Please don't be afraid of reading Sencha own code...

This is the override for the use case failing about reverting/reject/undoing/resurrecting a model deleted from a store.


From Store:



Code:



 rejectChanges : function() {
        var me = this,
            recs = me.getRejectRecords(),
            len = recs.length,
            i = 0,
            rec;


        for (; i < len; i++) {
            rec = recs[i];
            rec.reject();
            if (rec.phantom) {
                me.remove(rec);
            }
        }


        // Restore removed records back to their original positions
        recs = me.removed;
        if (recs) {
            len = recs.length;
            for (i = len-1; i >= 0; i--) {
                rec = recs[i];
                me.insert(rec.removedFrom || 0, rec);
                rec.reject();
            }


            // Since removals are cached in a simple array we can simply reset it here.
            // Adds and updates are managed in the data MixedCollection and should already be current.
            recs.length = 0;
        }
    }



From Model:


Code:



 reject: function (silent) {
        var me = this,
            modified = me.modified;


        me.rejecting = true;
        if (modified) {
            me.set(modified, me._rejectOptions);
        }
        delete me.rejecting;


        me.clearState();


        if (!silent) {
            me.callJoined('afterReject');
        }
    },


Code:



Ext.define('Ext.override.Model', {
    override: 'Ext.data.Model',
    clearState: function () {
        var me = this;


        me.dirty = me.editing = me.dropped = false; // Sencha bug, handling 'dropped' state
        me.editMemento = me.modified = null;
    }
});

It's very unlikely this use case would have been missed if using TDD.
