Question

Regarding to What is the best way to create various IndexedDB objectStores within the same script? I created two objectstores :

var opinionObjectStore = thisDb.createObjectStore("opinion", {keyPath: "id", autoIncrement: false});
var commentObjectStore = thisDb.createObjectStore("comment", {keyPath: "id", autoIncrement: false});

Then I open a transaction and get the both objectstore:

var transo = myDataBase.transaction(["opinion", "comment"], "readwrite");
var opinionsObjectStore = transo.objectStore("opinion");
var commentsObjectStore = transo.objectStore("comment");

Then I create my “need to be stored” objects:

var comment = {id: "myid"};
var resp = commentsObjectStore.add(comment);
// other instructions [...]
var opinion = {};
opinion.id = tagElement.id;
var resp = opinionsObjectStore.add(opinion);

And I get an exception:

DataError: Data provided to an operation does not meet requirements.
[Break On This Error]
var resp = commentsObjectStore.add(comment);

Could you help me to let me add my comment and don’t throw an exception?

I already read DOM IDBDatabase Exception 5 when adding data in indexedDB and Error "Data provided to an operation does not meet requirements" when trying to add data to indexedDB which do not help.

The problem is found:

tagElement.id;

If tagElement is a xml node from :

liveXml.find('Comment').each(function(){
    var tagElement = $(this);

Then tagElement.id is undefined, but tagElement.attr('id') is defined. jQuery matters!
