Record Specific Views in FileMaker
Adding DayBack to a Tab on a Contact or Showing Multiple DayBack Windows
You cannot embed DayBack directly into a record's layout and expect the calendar to automatically update with each record's events as you scroll through. Although it might seem like it works initially, FileMaker actually creates a new web viewer cache for each record. This will result in displaying outdated data and may eventually lead to memory issues.
Instead, consider using the button on DayBack's Sample Projects layout that filters the calendar to show events for a specific project. The script associated with this button, "Show Project in Calendar - DayBack," applies URL filters to focus the calendar on just one project.
For reference, you can find all the filters that can be set using this method here: DayBack URLs.
This limitation is also why attempting to open DayBack in multiple FileMaker windows might seem to work but ultimately does not. Claris never intended for the same web viewer to be used in more than one window.
