[Opensource] DBMaint fails on second search

[Luis]

Hello,

DBMaint fails on second search.

I'm very new to the Expresso framework, and DBMaint is still far to big for
me to locate the bug. But it can be reproduced taking the following steps:

1) Using DBMaint select table "MIME TYPES" from the General schema.
2) Click on "Prompt for search criteria"
3) Use "audio%" as filter for the MIME TYPE column and click"Display records
found by search"
4) A listing of 6 records appears.
5) Click on the binoculars to perform another search.
6) Leave all fields empty and click"Display records found by search" ...
Boom
No record is selected at all, when it should be retrieving all records.

Can you help me with this one ?

Thanks
