Impossible to use paymentReturn and Callback handlers

[voloships]

ERROR: "23000" (code N/A)
SQLSTATE[23000]: Integrity constraint violation: 1062 Duplicate entry '4-order_id' for key 'iname'

This error appears during paymentReturn or Callback (depends what goes the second).
In my case Callback goes after paymentReturn and fails with such error.

Problem is that both handlers are writing to the session cells table (xlite_session_cells) a same order.
Here is log backtrace:

Hi @svowl
I suppose "if cell exists" check works quite bad at classes/XLite/Model/Session.php(231)
That check allows to update cell even it already exists.

[voloships]

@svowl, please fix it in 1.0.24, it's very critical for my development.

We have created a ticket on this issue in our bugtracker system: http://bt.litecommerce.com/view.php?id=41457
The issue require some investigation. Please follow this ticket.

@svowl thanks, perfect.
But what possibility that it'll be fixed by end of June. We have release date in twenties of June and this issue is critical for us.
Also can you provide any estimates for release of 1.0.24?

Best regards.

Please sorry for the delay with resolving the issue.

If it is still actual for you, could you try to apply this patch to file src/var/run/classes/XLite/Model/Repo/SessionCell.php and check?
