Just to make sure we're on the same page: validKeyRegExp regexp shall match only if the payee string is _valid_, so if there's no match - the string shall be considered an _invalid_ payee matchstring.

Now, let's see what strings would be considered as (in)valid by both expressions:
[^ ] matches the following strings: "PAYEE", " PAYEE", "PAYEE ", "PA YEE", "P"
[^ ] does not match the following strings: "  ", " ", ""
^[^ ]*$ matches the following strings: "PAYEE", "PA YEE", "P", ""
^[^ ]*$ does not match the following strings: " PAYEE", "PAYEE ", "  ", " "

I believe the "[^ ]" regexp is correct.

The consequence of this mistake is that nearly all transactions will match the payee (to be precise: all transactions which contain at least one space in the 'payee' field).
