I have experienced this on two different computers using the same and different databases.  I can create Mass Update and Import specs and they function properly.  I can rename, update and save, and execute them.  But as soon as I make changes to the .dsr file and reconcile the database the specs disappear.  I believe I reported this during the beta testing under user 'hgihd'.  Thanks for looking into it.

Bluznjaz,

Specs will survive a Reconcile if they exist in the dsr. If a spec is in the db, but not in the dsr, Reconcile "believes" that you deleted that spec in Designer.

For the sake of user convenience, there are a few structural changes (like saving specs) which can be made in Sesame. To retain these through a Reconcile, before making your other design changes, you need to create a dsr that has these changes. You can do this by:

1. Redesign Current Application. This will create a dsr from your db in its current state, including the changes to specs. You can either save it as a new dsr, or overwrite the existing one. Your choice, depending on whether you like to retain versions of your design.

2. Open SDesigner standalone. From the File menu, select Open Application. Choose your db.  This will create a dsr from your db in its current state, including the changes to specs. You can either save it as a new dsr, or overwrite the existing one. Your choice, depending on whether you like to retain versions of your design.

Now, when you Reconcile, the dsr will have the changes that you made in the db.

If you prefer to use Designer for this task, you can open your dsr, create/rename/save your specs in Preview mode, then Reconcile.
