Using Submit operations with multiple tables that are nested isn't retrieving errors

[W1nstar]

When the response from the server is nested, and you're using submit = true, the _mergeUpdateForSubmit function triggers on a successful request.

When this function reads the JSON the server has answered with, it is only accessing first-level tables, therefore it isn't retrieving errors server is returning in child tables, deeming operations as successful.

	var dataSetJsonObject = jsonObject[this._dataSetName];
	if (dataSetJsonObject[this._dataSetName])
	dataSetJsonObject = dataSetJsonObject[this._dataSetName];
	var beforeJsonObject = dataSetJsonObject["prods:before"];
	for (var buf in this._buffers) {
	var tableRef = this._buffers[buf];
	var tableJsonObject = dataSetJsonObject[tableRef._name];
	if (tableJsonObject instanceof Array) {
	for (var i = 0; i < tableJsonObject.length; i++) {
	var recordId = tableJsonObject[i]["prods:clientId"];
	if (!recordId) {
	throw new Error(msg.getMsgText("jsdoMSG035", "_mergeUpdateForSubmit()"));
	}
	// Determine if error string (get prods_id before _mergeUpdateRecord() is called,
	// since it removes all prods properties)
	errorString = undefined;
	if (tableJsonObject[i]["prods:hasErrors"]) {
	var prods_id = tableJsonObject[i]["prods:id"];
	errorString =
	this._getErrorStringFromJsonObject(dataSetJsonObject, tableRef, prods_id);
	}

Here, dataSetJsonObject holds a NESTED dataSet, so only one table is present, rest are nested inside:

Line 5534 in 319202b

var tableJsonObject = dataSetJsonObject[tableRef._name];

Only table is gonna see error processing is the initial table, while errors may occur on child tables.

Is there any workaround for this? useRelationships does nothing in this scenario.
