Something I noticed when working on some named queries today:
Steps to recreate:
Create a named query
Set the database connection to “parameter” while there are still parameters defined for the query
Delete all parameters for the query
When attempting to delete the final parameter, the designer freezes up and cannot be recovered.
This can be worked around by temporarily setting the database connection to “default” and then deleting the parameters and setting the database connection back to “parameter”.
Since posting, we’ve generally moved away from named queries because stored procedures made more sense for the architecture of our project. We recently upgraded to 8.0.3. I just tested this again and got the same issue though. I was actually unable to delete any named query parameters once setting the database connection to be parameterized.
