InvalidStateError in Firefox

In FF v27.0.1 occurs error:

asyncStorage: can't open database: InvalidStateError
InvalidStateError

in this code:

var openreq = indexedDB.open(DBNAME, DBVERSION);

In Chrome v32.0.1700.107 m everything works fine. Could you help me?

Thanks @thgreasi that is working for me in your example pen and by testing your branch in my own application. I had tried .stopPropagation() (didn’t work) but got dragged away before trying out .preventDefault(). Thank you for investigating and resolving this!

I can’t see any other side effects to this. Also, it sounds like FF’s behaviour here is the “right” behavior with regards to propagating the errors to window.onerror (see “Integrate with window.onerror” in the w3c/IndexedDB spec) so it does look like this is the right thing to do.

Not directly related, but why does the .onerror handler reject with openreq.error rather than the error passed in to the handler?

I didn’t, but most browsers don’t fail there 😃 I don’t have a large suite available for testing sorry. My colleague reported to me that .ready resolves rather than rejects in Safari private browsing mode though, even though there are no valid engines available.

I’m not sure that they’re the same object; if multiple errors occur then it would only be the most recent one, so possibly can’t be relied on. Not sure whether that’s possible or not when opening a DB though, I suppose the first error aborts it and so no more occur. Not on a computer to check equality right now, but I did have an error calling preventDefault on the openreq.error object rather than the passed in error, so they may not be the same in FF (although that does seem weird, so maybe the error was mine).

Did you got any weird results on other browsers?
