In New York and previous releases, opening an existing record on a parent table, but then selecting a record from a child table, used to produce a helpful descriptive message explaining which table was expected to open and which table actually opened. In early Paris the test would fail with "the form failed to load" which lacks useful information.
FAILURE: Failed to open the 'task' form with id '4d9fb984db231010542ae8cd1396194b'
This problem was fixed in Paris Patch 1 and onwards.
To prevent this failure, review the Open an Existing Record step to ensure the table and record's table are the same.
If they are not the same, upon seeing the "The form failed to load" failure, turn screenshots on to view the record that was actually opened in the ATF test, and ensure this is the same table as set in the Open an Existing Record step.
