Remote Data - when empty results are returned - pager not updated

[Webauthor]

Hi, I use an external filter on my grid and when I search and results come back, everything works great, but if I get back an empty array, the pager does not update.  See

With 0 results:

I'm using the latest version (3.3.2).  Any insight?

I assume you have been using remote paging and remote filtering. In case of remote paging, the grid & pager takes totalRecords, curPage, data values from getData callback, so it's up to the remote script to send correct values of theses variables.

Code: [Select]

getData: function (dataJSON) {
        var data = dataJSON.data;
        return { curPage: dataJSON.curPage, totalRecords: dataJSON.totalRecords, data: data };
}

You should update the totalRecords, curPage variables on the server side scripts values when filtering takes place as they are ultimately passed on to getData callback.

Hi, I do return that.  In the case of an empty result set, I return 1 for curPage, 0 for totalRecords and [] for the data property.

Here's an example:

Try adding a filter for Activity Type : Greater Than : then use 44 first, then 444 then 4444 until you see 0 results.

Any ideas why it is not updating?
