Updating an Ext JS 3 app, finally forced me to need Condor's Ext.ux.data.PagingStore extension, since I couldn't find one amongst the 270+ posts on the thread at http://www.sencha.com/forum/showthre...gingStore-v0.5.

Code is at: https://github.com/aghuddleston/Ext.ux.data.PagingStore

The main difference from the Ext JS 3 version is that start, limit and page are no longer part of params, but are their own properties on the options config used during store load.

Example remote store (note last options):
PHP Code:
     var myStore Ext.create('Ext.ux.data.PagingStore', {
         
model'User',
         
pageSize3,
         
lastOptions: {start0limit3page1},
         
proxy: {
             
type'ajax',
             
url'url/goes/here',
             
reader: {
                 
type'json',
                 
root'rows'
             
}
         }
     }); 
Example local store:
PHP Code:
    var myStore Ext.create('Ext.ux.data.PagingStore', {
         
model'User',
         
pageSize3,
         
proxy: {
             
type'memory',
             
reader: {
                 
type'array'
             
}
         },
         
datadata
     
}); 
My goal was to match the behavior of the Ext JS 3 version, so it should only request new data if params or extraParams changes, otherwise it is just paging through the existing store. To force a reload, make sure to delete store.lastParams before store.load is called.

It is very lightly tested so far, with Ext JS 4.1.1. Feel free to fork, push/pull etc for any needed changes/enhancements.
