PagingMemoryProxy doesn't obey SortInfo

[shaun]

I have had issues with sorting of elements in a DataView that seems to only appear if I associate a PagingToolbar with the store that is feeding the DataView. After a bit of looking, I found that the PagingToolbar creates a PagingMemoryProxy for the store which doesn't look at the SortInfo object ... it only looks at params.sort, which seems to only be set by grids...

I take it back... the PagingMemoryProxy seems to sort the Store's elements on a page by page basis. That is, it pages and then sorts - when it should actually sort and then page.

Since my Store is entirely on the client:

    <ext:Store runat="server" ID="Store1" AutoLoad="true">
        <Reader>
            <ext:JsonReader>
                <Fields>
                    <ext:RecordField Name="id" />
                    <ext:RecordField Name="name" />                   
                </Fields>
            </ext:JsonReader>
        </Reader>
        <SortInfo Field="minhost" Direction="ASC" />
        <AutoLoadParams>
            <ext:Parameter Name="start" Value="0" Mode="Raw" />
        </AutoLoadParams>
    </ext:Store>

I would certainly expect sort then page.

Interesting find.

We'll look into this and come up with a fix.

I tried to make that code generic, and ended up missing one spot. The "minhost" reference in sortinfo is actually "name".

Also, the store has remoteSort = false.

The sample attached to http://forums.ext.net/showthread.php?4385 is a pretty good demo of this sorting issue.

Hi,

You need to set RemoteSort="true" for Store. It will force to move the sort params to the proxy

Thanks Vladimir that worked perfectly!

The name "RemoteSort" doesn't really indicate to me that it would push sorting to the client... perhaps this should be called "ClientSort"?

Hi,

RemoteSort means that sorting will be performed outside the Store (in proxy like PagingMemotyProxy or sort params will be moved on server side like in HttpProxy).


If RemoteSort="false" the sorting will by performed by Store (on client side)

Thanks for the clarification.
