jQuery Grid Plugin - jqGrid

Hi,

I am using the jqGridExport/Import functions and have come across a potential bug when using  postdata with setGridParam.

If I do a search with the grid and then hit the default reset/reload button on the pager, and then export my grid I get non-valid json in the form of:

...

"postData":{
            "_search":false,
            "nd":1266945818052,
            "rows":5000,
            "page":1,
            "sidx":"BLDRM",
            "sord":"asc",
            "filters":"
        },

...

as you can see there appears to be an unescaped quote for filters

BUT if i create my own reset button using the code below:

jQuery("#showBuildings").setGridParam(
                {
                    postData:
                    {
                        serialString : "status=1",
                        filters:null
                    },
                    page:1,
                    search:false
                }
            ).trigger("reloadGrid");

I am able to get the export to function as expected:

...

"postData":{
            "_search":false,
            "nd":1266945392829,
            "rows":5000,
            "page":1,
            "sidx":"BLDRM",
            "sord":"asc",
            "filters":null,
            "serialString":"status=1"
        },

...

Any attempt to use filter:'' or filter:"" will cause the export to produce invalid json, only null seems to produce valid results.

does this seem like a bug to you?

thanks
