    <p>The fact that you have to manually update (and commit) the subrepository is very much intentional. This misfeature found in CVS and SVN was intentionally left out.</p> <p>If it would automatically update subrepositories to the latest commit, there is no guarantee that code will remain working. E.g. if you would change the API of C, neither A nor B will work until you change them accordingly. And because you can never push multiple repositories atomically at the same time, there would unavoidably be a window during which A and B do not work. In practice, this window can grow rather large, especially as soon as one of those depending projects receives less development attention. And if project B would be put on hold for a while, the changes to C for project A would break it in no-time.</p> <p>Worse, updating to an earlier version would not be able to restore the subrepository to the state it was in at the time. So as soon as you would make a backwards incompatible change to the subrepository, older versions would not work anymore! This greatly reduces the usefulness of version control. It would cause problems with branching and e.g. bisecting would not be able to work.</p> <p>This is why you are required to manually update to the latest version of C, test whether everything still works, and check in that subrepository update. Thereby tightly locking the repository version to the subrepository version. You sacrifice a little bit of convenience, but you gain code stability, and I hope I was able to make clear why this is much better :).</p> <p>As for transparently committing to a subrepository from within a parent repository, as far as I know it is planned to do this but so far no-one has actually implemented it.</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
