Jqgrid on Edit operation sends "add" as oper="add" why? - jqgrid

Question

I have a weird one. After changing the data store from session to oracle, when i hit Edit on the 'inlineNav' it always goes to the server with the "add" operation. Any ideas why this could happened?
$("#assessmentproduct").jqGrid({
url: 'orthofixServices.asmx/GetProductList',
colNames: ['id', 'Product Description', 'Commission Rate'],
colModel: [
{ name: 'id' },
{ name: 'description', index: 'desc', width: 170, editable: true },
{ name: 'commissionrate', index: 'com', width: 80, editable: true, unformat: percentUnFormatter, formatter: percentFormatter, editrules: { number: true} }
],
serializeRowData: function(data) {
var params = new Object();
params.id = 0;
params.prdid = parseInt($("#prdid").val());
params.description = data.description;
params.commissionrate = data.commissionrate;
return JSON.stringify({ 'passformvalue': params, 'oper': data.oper, 'id': data.id });
},
mtype: "POST",
rowNum: 4,
height: 93,
width: 400,
pager: '#assessmentpager',
editurl: "orthofixServices.asmx/ModifyProductList"
});
$("#assessmentproduct").jqGrid('navGrid', '#assessmentpager', { add: false, edit: false, del: true, refresh: false, search: false }, {}, {}, { serializeDelData: function(postData) {
return JSON.stringify({ 'passformvalue': null, 'oper': postData.oper, 'id': postData.id });
}
});
$("#assessmentproduct").jqGrid('inlineNav', '#assessmentpager', { addParams: { position: "last", addRowParams: {
"aftersavefunc": function() { var grid = $("#assessmentproduct"); reloadgrid(grid); }
}
}, editParams: { "aftersavefunc": function() { var grid = $("#assessmentproduct"); reloadgrid(grid); } }
});

You use JSON.stringify inside of serializeRowData to serialize the posted data to JSON. It's the reason of the encoding which you describe.
UPDATED: OK! Now I see at the end what's the problem. The reason of the misunderstanding was because you used oper="add" in the title instead of oper=add. I understood you that this is your problem (sending of quoted oper="add" instead of oper=add). OK. The problem with sending of oper=add in case of edit operation is known jqGrid bug which is already fixed in the code on the github (see here). You can make the same changes in jquery.jqGrid.src.js and use the fixed code till the new version of jqGrid will released.
