Transactions disappearing before match dialog

[Jon Schewe]

I'm trying to track down an issue where I am not presented with the
transactions that I expect for some checks matching. I have a
particularly difficult situation for GnuCash to match in that:
1) the checks are always the same amount
2) the checks are written a week apart
3) the checks are cashed up to 2 weeks after written
4) the back does not include the check number in the OFX file

I understand that I can double click on the match dialog and choose
from all possible matches. However I'm finding that the match that I
desire isn't showing up in the list.

I've added debugging to split_find_match to try and track it down. At
this point I'm finding the transaction that I desire being added to the
list of possible transactions in this method. The method exits with 3
transactions. However when the dialog is opened I only see 2
transactions. I'm always missing the one that I want.

I see the split_find_match is called from perform_matching and that it
calls gnc_import_TransInfo_init_matches after all matches are found.
At this point I have the correct number of transactions in match_list.
However I don't know the gnucash source or gtk well enough to be able
to figure out the steps between there and when the dialog that let's me
pick transactions is built and displayed.

Can someone help point me to the flow of execution between these 2
points?

Thank you,
Jon
