Cms3 dashboards and absolute URLs

All,

  First, I wanted to give a big thanks to all who contribute to this: what an excellent and useful system for tracking & displaying sensor data!

  I did notice an issue that I thought I should bring up: it might be user error, but it wasn't obvious how to remedy (and I didn't find anything posted when I searched the site):

Dashboard visualizations are stored in the dashboard table with absolute URL's.  If the system is moved to a different network segment, of gets a different IP at reboot, the dashboard view still references the original URL, giving errors for all charts.

If this happens to anyone: one temporary workaround is to use an SQL query to replace the old IP with the new IP:

update content from dashboard set content = replace(content, 'old_ip', 'new_ip');

Of course, this only works until the next IP change...

Is there a good reason that the dashboards don't use relative URL's?

Thanks!
