HBCI Advisory: Cancelled transfers might be sent twice (was: Re:

Problem: As Eildert pointed out a few minutes ago, the HBCI code in
GnuCash under special circumstances may have the possibility of sending
the same online transfer ("Überweisung") twice. This will happen if an
online transfer has been correctly queued, i.e. the user pressed "Ok",
BUT then the execution got cancelled due to a) chip card problems, b)
cancelling of the PIN entry dialog. *IF* you invoke another HBCI action
*during* that very same gnucash session, then in fact the queued
transaction will be executed even though it looks like it has been
cancelled. If gnucash is exited, the queued transaction will disappear
since it is stored only in memory, and no cancelled transaction will
appear as duplicate.
Workaround: If the execution of an online Transfer ("Einzelüberweisung")
has been cancelled, e.g. due to chip card problems or cancelling the PIN
entry dialog, you *must* *exit* GnuCash and *restart* it again *before*
invoking any further HBCI actions.
Affected versions: This bug affects all versions of GnuCash with HBCI
support, up to and including the current stable version 1.8.1.
Fix: This will be fixed by me tonight in gnucash CVS. The next stable
version 1.8.2 which have this problem fixed is not yet scheduled for
release, but this will probably take another 2-3 weeks.
Sorry for this problem.
