The Revert To Previous Version button is available from the Contents page (in all editions) and the Info page (in Enterprise edition) of the history view. When you click the Revert To Previous Version button the Revert Confirmation dialog box displays.
Reverting to a previous version makes the targeted version the most current version again. Reversion eliminates everything in the editor buffer, but nothing else. This means that any changes you made since last saving the file will be lost, but any saved versions of the file between the version you're reverting from and the version you're reverting to will be preserved.
When using backups, check your backup level. Once the maximum number of backups is reached, the oldest version will be thrown away and all the versions above it will be renumbered, so that the former version number 3 will become version number 4, and so on. This preserves the most recent work.
Version control is a feature of JBuilder SE and Enterprise:
If the file is under version control, the repository version of the file is unaffected by reverting. You must check the reverted version into the repository in order to post the change. That way, the reverted version can be assigned the latest version number and other developers can access the reverted version of the file.
