Hi,
I really appreciate your help with this, and I'm sorry to keep bothering you about the boolean thing, but:
It seems the recent successive changes to the boolean parameter are conflicting with one another (some changes made to the testing framework and others to the rest of galaxy).
At changeset 3402:bb50ac713feb (before the whole boolean issue start), testing "gpos_concat_1" works OK - single tests the succeeds (and only tests the "true" case).
At changeset 3410:4a416d872806 (which fixed the boolean in the testing framework), testing "gpos_concat_1" works OK - with two tests, checking both "true" and "false" cases.
But changeset 3411:0c07212afc00 (which fixed the boolean bug not related to testing framework) broke the testing framework entirely: testing "gpos_concat_1" fails on both tests (together with all my tools which have a boolean parameter, even if those tests worked before).
