jQuery Grid Plugin - jqGrid

Currently, when you load data using the addJsonData method and the datatype is 'json' and you try local searching, all of the rows simply go away, instead of properly filtering the grid. By changing the datatype to 'jsonstring', the problem goes away and the local searching performs as expected (no change is needed to the incoming data).

Steps to Reproduce:

Create a grid with datatype: 'json' and do the following:

1) Load data to the grid using the addJSONData method.

2)Perform local search. This is how I am currently doing it:

   var grid = $('testGrid');

   var postdata = grid.jqGrid('getGridParam', 'postData');

   $.extend(postdata,

     {

filters: '',

searchField: 'colname'

searchOper: 'eq'

searchString: 'test'

     });

     grid.jqGrid('setGridParam', {search: true, postData: postdata });

     grid.trigger('reloadGrid', [{page: 1}]);

3) You will notice that the rows disappear instead of being filtered. Now change the grid's datatype to 'jsonstring' and try again. You will notice that the rows are properly filtered.

I have found the bug in the grid.base.js file in version 3.8.2 at line 1167:

locdata = (ts.p.datatype != "local" && ts.p.loadonce) || ts.p.datatype == "jsonstring";

Changing the line to the following causes it to work with datatype 'json'

locdata = (ts.p.datatype != "local" && ts.p.loadonce) || ts.p.datatype == "jsonstring" || ts.p.datatype == "json";

jqGrid version: 3.8.2
