Testing log - original intent was to see if there's an obvious problem with export/import
Created new project, filename Test1.osbk according to the screen that created it, a long novel with 2 parts and 2 chapters.
Tried to open it. Found Test1.mv.db. Which had no parts and no chapters. Also no genders, categories, or strands. In former versions some defaults for these were provided automatically.
Created a part, "part a", part number 1. No problem. If the supposedly-created parts existed, I would have expected a collision on the part number.
Created a chapter, "chapter a", within "part a", ditto.
Could not create a scene.
Created a location.
Could not create a character until after I created a gender and a category. ("gender a" and "category a", then "character a", of course)
Created a strand, then could create a scene.
(Being extremely familiar with database design, I understand these requirements once I found them. However, I shouldn't have had to guess or hunt for them. Being told why something doesn't work is helpful. Clicking a button and having absolutely nothing happen, usually isn't.)
Saved it. After save, filename was changed to "Test1.osbk".
Exported it in database format.
Closed & restarted the program. Created new project, "Test2.osbk" which of course was named "Test2.mv.db"
Tried to import the database.xml file from "Test1". Set up no problem, but clicking the "Import" button simply caused the button to be highlighted. Doesn't matter whether the "Replace all existing" checkbox is marked or not. It doesn't lock up though - the "Cancel" button works.
Manually examined the database.xml file. Nothing obviously wrong with it. Parts are in order consistent with the above-discovered requirements.
Renamed the file, exported the Test2 database.xml, and renamed that too. Examining that, found a few headers and no real content - as expected.
Tried to import Test2 database.xml. "Import" button would not even enable, which is appropriate since the file essentially has no content.
Saved Test2 even though nothing had actually changed. Filename suffix changed to osbk.
