So the exception comes up because of this 'oldKeys' data being sent. Naturally, its value being: {"undefined":"ext-record-141"} does not quite look right.

This value comes from this line of LABKEY.ext.Store:

getOldKeys : function(record) {
        var oldKeys = {};
        oldKeys[this.reader.meta.id] = record.id;
        return oldKeys;
    }

I do not have this.reader.meta.id and the record.id does not have anything meaningful in it...


this.reader.meta

Object {title: "gstbl", totalProperty: "rowCount", importTemplates: Array[1], root: "rows", description: "↵ The 'gsTbl' table contains information about generated gating sets.↵ "…}
description: "↵ The 'gsTbl' table contains information about generated gating sets.↵ "
fields: Array[8]
importMessage: null
importTemplates: Array[1]
root: "rows"
title: "gstbl"
totalProperty: "rowCount"
__proto__: Object


record

sb {phantom: false, id: "ext-record-3", data: Object, json: Object, store: LABKEY.ext.Store.Ext.extend.constructor…}
data: Object
dirty: true
id: "ext-record-3"

phantom: false

So what needs to be done here, guys? Anybody?
