[TYPO3-shop] handleScript call without finalize

[Richard Hirner]

Hi,

Is there a way to call a handleScript without finalize? E.g.,

/basket.html?products_finalize=1&products_cmd=prepare

would call the handleScript with GP var products_cmd set to prepare.
The problem is that because finalize is set, the order is finalized
although the script did only prepare the payment but did not finish it
(e.g. because of an error). =>

How can I call the handleScript without finalizing? Or, if this isn't
possible, how can I cancel the finalization if there is an error in the
handleScript?
